Just saw this tweet from @Musclenerd – from iPhone Dev Team, the iOS jailbreak authority.
Because there’s no 4.3 beta for iPhone3G, it’s effectively unlocked for life via the 06.15 ultrasn0w unlock.
It is so true!
If you noticed, there was a slight uproar (if you listened hard) that iPhone 3G was left out when iOS 4.3 beta 1 was released.
But, there is a good side effect (atleast for some) from Apple not supporting iPhone 3G with iOS 4.3. This means Apple is now going to block the current ultrasn0w 06.15 unlock with a firmware/baseband update.
Your iPhone 3g is unlocked for life!
