[Question] [Solved] Can I upgrade an unlocked iPhone 3G to Firmware 2.1?

I have just bought an iPhone 3G which appears to be unlocked here in India since I can use Sim card from any carrier without use of any hardware eg. Any Sim / Turbo Sim etc. The phone is already activated and has all the setting usually hidden eg. Cell Data Network etc.. except for the fact that it is not jailbroken.

Can I upgrade the Firmware from 2.0.1 to 2.1 without locking the phone.

Is there a way to find out from which country the unlocked iphone was shipped? Or do you think I should be bothered!

Is there a way to image the phone so that if things don't work out, i can restore the same back to its original unlocked state??

Please , Please HELP!!!!!

An unlocked phone stays unlocked, no matter what you do. THat's why you pay the extra price.

Apple has a section whre you can check the serial number and see what country it is from.

Hey thanks John,
I did update to 2.1 and then used QuickPwn to jailbreak it. I worked like a charm.

But one more problem I have which is related to the AppSupport or caller ID matching. The Caller ID fix available on Installer and Cydia work on my iPhone 2G but when i installed it on my iPhone3G, it does not work.....

Can you Help????

As a matter of fact, I'm still waiting for my iPhone 3G I bought on ebay, so I can't help you out with that. :( Sorry.

I am using the 3G unlocked by a turbo SIM, so was just wondering; does same work for an iphone unlocked using a turbo SIM? I mean is there any way the SIM won't trick the new Firmware?! Or the unlock does not have to do with the FW?!

thx

yeah if an iphone 3g is unlocked by a turbo sim would i be able to upgrade to all firmwares and new upcoming firmwares without it getting unlocked?

@KolIphone & at004

Only (official) factory unlocked iPhones will. Nobody knows if *sim will be working on upcoming fw updates. I'd put some bucks in a "NO" - we'll see

ok thanks for your answer, i just have one more question, lets say that the iphone has the turbo sim built inside it and on a new firmware it will not work, however there is a software unlock available, will the software unlock work with the turbo sim still inside the iphone 3g?
