How to upgrade to iPhone 3.0 beta on iPhone or iPod

If you have completed download of iPhone 3.0 firmware then you can go for update or you can download iPhone 3.0 firmware from my post FREE Download iPhone 3.0 Beta Firmware both direct and rapidshare download link. Before we begin, let me warn you that it is an advanced level hack so please proceed ONLY if you have a clean understanding of what you are doing. I strongly recommend users with unlocked iPhones to wait till the iPhone Dev team releases a patch for the new firmware. Following procedure is applicable for those with a AT&T locked iPhone and all iPod Touch users.In this hack we will see installing iPhone 3.0 firmware both i iPod Touch and iPhone 2g/3g.


Installing iPhone 3.0 firmware on iPhone 2g/3g

1.Make sure to have downloaded the iPhone 3.0 beta firmware that relates to your iPhone (2G or 3G).
2.Extract the firmware IPSW to a folder.
3.Connect the iPhone to your computer.
4.Get the UDID registered on the iPhone Developer program.
5.Open iTunes and click Restore while holding the Shift key (for Windows) or Option key (for Mac).
6.Locate or browse to the firmware IPSW.
7.Wait for iTunes to unpackage and install the firmware.


Installing iPhone 3.0 firmware on iPod Touch

iPod Touch users are pretty safe in this case as there is no question of baseband like iPhone but their is still a catch which I shall be mentioning further below.
01.Once the firmware has been downloaded, extract the IPSW to a folder.
02.Connect the iPod Touch to your computer.
03.Get the UDID registered on the iPhone Developer program. (How to?)
04.Make sure to disconnect from Internet such that iTunes cannot communicate with the web.
05.Only then, open iTunes and click Restore while holding the Shift key (for Windows) or Option key (for Mac).
06.Locate or browse to the firmware IPSW.
07.Wait for iTunes to unpackage and install the firmware.

Note: Step-3 is optional for iPod Touch users but in case you decide not to get your UDID registered, you won’t be able to Sync with iTunes. The upgrade method is valid for both iPod Touch 1st Gen and 2nd Gen.

I again repeat - after upgrading to iPhone 3.0 beta, you might not be able to downgrade to firmware 2.2.1 later on so it is always a good choice to wait for the official release which is due in summer. iPod Touch users are always safe but I have already clearly warned the iPhone users to proceed at their own risk.

Keep checking back for more hacks and tips related to the iPhone, I shall be publishing more of it soon.
