How to Unlock your iPhone 3G
The biggest news for 2009 so far is the YellowSn0w unlocking application for the iPhone 3G. You can now insert any SIM card into your iPhone 3G — good news for consumers, bad news for telcos.
The “yellowsn0w” application works with the latest iPhone 3G modem firmware (02.28.00) so if your iPhone is not yet on 2.2, just hook it up on iTunes and upgrade it before unlocking.
I have yet to do this on my iPhone 3G so I’ll update this post after I make a successful attempt (initial reports from other unlockers revealed that close to half of the attempts weren’t any good).
