A Must Read about buying i-phone 3 G Review
Friends …..those of you in India planning for iPhone… THINK TWICE BEFORE MAKING A DECISION… The short comings of iPhone are endless…
No video calling,
no AD2P on the Bluetooth, (No Stero BT headset)
CAN’T share ANY (mp3, images,videos….) files via bluetooth,
can’t use as a wireless modem, (you pay ridiculous data charges to activate internet on your phone, but cannot connect it to your PC and browse when you are at home)
no copy and paste,(cannot copy a part of a…. say…. email & send it….have to type it out yourself)
no 3.2 or 5 megapixel camera,(the 2MP camera it carries is worst camera i’ve ever seen….. photos look like they have come out of a VGA camera)
no video recording with camera,
no front camera,
no flash.
no JAVA support
No physical keyboard (BELIEVE me! this alone is a dealbreaker…touch keyboard as good as it looks…once you use it then only you come to know about the importance of having a hard keypad)
No 3G network yet in India..so why pay for expensive 3G phone if you cant use its 3G services … so, for India, iPhone 2.0 is no better than its first version
No removable battery. (You cannot change battery. Have to send it to apple outlet.. Come on now!!!!…This is not an iPod. Its a phone. You cannot live without phone for 2-3 days)
No haptic feedback and
cannot send MMS,
can’t use as external storage device (16 GB of utter waste..next time you go to your friend’s house & find some interesting songs, movies, etc…sorry you cannot connect your ‘16 GB’ phone and share it!!!! Apple apparently has a solution.. ” BUY MUSIC & MOVIES FROM iTUNES STORE “….. Give me a break will you APPLE!!!)
no FM radio,
can’t use your mp3 files as ringtones,(This is heights man!!!)
cannot insert any other SIM card….
completely tied to iTunes… Connect to your friend’s iTunes & you risk erasing everything on your phone.
list goes on & on & on….
We Indians are used to these features. Most of our phones already have these features. & we cannot do with out them…. i mean can you imagine paying so much for a phone with which you cannot transfer files via bluetooth. what age is this …STONE AGE???
Some features may be activated by jailbreak.. But why the hell should you risk losing your warranty after paying so much.
And want to add third party softwares??.. YOU HAVE TO BUY THEM FROM iTUNES STORE ONLY!!! . (Shell out more money). Apple is a bloody control freak. Dont surrender your freedom to it.
Its good for american market (who have no idea what mobile freedom/choice is) which is in stone age compared to asian/european markets. When they want to buy a phone, they have to go to network operators and buy only those phones that are available on that network. & stick to that company till their contract expires. You want to change carriers? Not before paying damages, & buying another phone on the other network again.
On the contrary, we in India have so much freedom. We go to handset shops & buy which ever phone we like. Then go to carriers.. checkout the plans & buy SIM.. Dont like the plan or rival carrier came up with a better plan???? EASY .. just remove & replace the SIM.
Apple are trying to IMPOSE THEIR MODEL ON US riding on the hype iPhone has created in the US (yes it was a flop in Europe .thats why Apple never talks about its sales in Europe).
Dont fall for the subsidized price of iPhone… CHECKOUT THE DATA PLAN ATTACHED TO ITS SIM ..they will recover the cost through ridiculous data plans. Bill might come to around Rs 2500/month.(ATLEAST AMERICANS PAY THAT MUCH)
Let me clear one thing though.. iphone is the best looking phone (its touch interface is nothing like you have ever seen ), & best browsing experience out there no doubt …. (& others are fast catching up..check out the android demo at Google IO 2008)…. BUT AFTER A FEW DAYS IT ALL COMES DOWN TO FUNCTIONALITY…
Those of who buy it… You will be most happy for atmost a week… & then, MARK MY WORDS…YOU WILL START REGRETTING IT!!!
So friends lets spread this info to all our friends and help them in making a wise decision….. & those of you who have bought unlocked versions already please share your experiences with others
THANKS FOR YOUR TIME…. GOODLUCK!!!

Browser FAQ’s
Check browser properties
Q: Can I check whether Java is enabled in the browser?
A: The method to check whether Java is installed and enabled is navigator.javaEnabled(), which returns a boolean value.
Q: How can I get the operating system the browser is using?
A: You can read the application version of the browser that executes your Javascript code from the navigator.appVersion property. This string is part of the user agent identifier that the browser sends to a server when it requests a Web resource and usually includes the browser version number and an indication of the operating system the browser is running on.
This property may be interesting purely for information, but you should be cautions about how you interpret its contents and avoid using it to control script execution. In many browsers, the user agent string can be modified to “spoof” as a different browser type, use arbitrary text or withhold any user agent information at all.
Controlling the browser
Q: Can I set the printer properties using Javascript?
A: No, the Javascript object model includes a window.print() method that may activate the standard print dialogue of a Web browser, but that is as far as the functionality extends. It would not be appropriate or safe for Javascript code to be able to check the printers attached to a computer, look up printer properties or arbitrarily configure their settings.
If you want to influence the way a Web page is printed, you will find it much more effective to use Cascading Style Sheets for print media. See the Media style sheets FAQ for further details.
Q: Can I select a particular printer using Javascript?
A: There is no DOM standard object reference to system printers and therefore no Javascript or ECMA script application programming interface for selecting amongst available printers. The basic DOM level 0 function for printing is window.print(), which should raise a print dialogue. Whether users have any printer attached to their computer, decide to choose amongst them and to commit the print job is outside the control of Javascript. It would be a security hazard if Web page scripts could arbitrarily control computer peripherals and expend paper and ink without user intervention.
Q: Is there a method to clear the browser cache?
A: It should not be possible to clear a browser cache using Javascript because this would be a security hazard.
Q: Is there any way to enable Javascript if it is off?
A: There is no way to switch on Javascript in a Web browser if it is not enabled. It would be a serious security hazard if code in Web pages could override users’ browser settings in this way.
People choose to switch off Javascript because some Web developers mis-use Javascript to affect the way their browser works; typically with pop-up windows and redirects to pages they have not chosen to visit. Some Web browsers do not support Javascript at all, so your Web pages should be designed to provide useful information for people without Javascript.
Locking down the browser
Q: How can I suppress the print dialogue?
A: It is always a bad idea to try to stop people’s Web browsers working the way they expect. There are very good reasons for a print dialogue to be shown; so that it can be cancelled in case print was requested by mistake, so that the settings can be adjusted as required for the content, so a different printer can be selected. Can you be sure they actually have a printer connected?
You should re-consider why you want to disable the print dialogue and perhaps provide more guidance to the user about what you would like them to do. The media dependent style sheet FAQ may give you some further ideas.
Q: How can I suppress Ctrl+N for new window?
A: It is never a good idea to stop people’s software from working the way they expect it too. You should re-think why you would want to do this. If there is some shortcoming in your application design? Don’t try to break your users’ Web browsers to work around it, they will not thank you for it.
The Ctrl-N keyboard combination is probably one of the least commonly known ways to open a new Web browser window and there are several more obvious ways to do so anyway.
Q: How do you disable view source and save image options?
A: It is never a good idea to stop people’s browsers working the way they should and you should look again at why you want to stop them doing things that are fundamental to the Web. There are techniques that can make these operations difficult, but they can be overcome simply by switching off Javascript in the Web browser or using a different client.
Any efforts to stop people taking copies of content that is published on a public Web address are futile and likely to impair the usability of your site. If you do not want to risk the possibility that people will take copies of your source code and images, do not publish them on the Web or find a different way to achieve your goals.
Q: How do I disable the “Save As” option in IE using Javascript?
A: This is another example of something you should not attempt to do with Javascript, it is never a good idea to try to prevent a person’s browser working the way it is intended, some would regard it quite hostile. In this case, the objective is completely futile; any HTML, image, Javascript or CSS that is published on the Web is completely in the open and can be saved in numerous ways. In most cases Web resources are immediately saved in the browser cache.
If you are trying to protect a digital resource that is truly valuable, you should not make it available on the Internet.
Q: Can I use Javascript to disable the browser cache?
A: It is not possible or desirable for Javascript code on a Web page to disable fundamental browser features such as URL resource caching. You should re-think the issue you are facing and consider a different way to tackle it. For example, you can set HTTP headers to request resources are not cached, and that cached resources are refreshed after a specific period, or that the freshness of cached resources is checked before re-loading a page. Web user agents are not obliged to follow these directives, but most will be configured to do so. See the Site manager FAQ for cache configuration examples related to stylesheets.
