Yes, you read that right! If you happen to be one of those lucky Lukes with the iPhone 3G (and if you just got yours from Christmas), then read on. The iPhone Dev team has released the unlocking tool (code name: yellowsn0w) that shall permit the iPhone 3G to work with any carrier.
If you have been following this development, note that contrary to what was posted earlier, the tool does indeed work with the latest firmware version, 2.2, which contains the latest radio baseband.
Things to note before attempting to modify your iPhone 3G:
- the unlock tool only works with baseband 02.28.00, which is provided by the recently released firmware version 2.2
- the unlock tool is designed as a daemon (background process), thus there’s no GUI
- version 0.9.4 has been released which relieves the need for a one-minute delay upon resetting the iPhone
- you’ll need to jailbreak your iPhone in order to run the unlock tool
Head over to both the iPhone Dev‘s site for further reading, and yellowsn0w to download the tool.

Hack at your own risk!
P/S: No, this will not work on your iPod touch 2G

I am running firmware 2.2.1 on my iPhone 3G and have tried to run yellowsn0w several times but my iPhone is still locked!?!? Anyone have any ideas?

Has anyone had any success upgrading to 3.0 beta yet?
