iPhone 3G on BaseBand 06.15.00 Unlocked for Life

It�s official. If you have an iPhone 3G on baseband 06.15.00 and you are unlocked , you better get comfortable.
MuscleNerd confirmed in a recent tweet that since the iPhone 3G will not be receiving the 4.3 firmware upgrade, your iPhone 3G will remain unlocked indefinitely.
Now let�s not all panic, this only affects iPhone 3G users on the above mentioned baseband. If you are unsure of your baseband version, you can go to settings -> general -> about -> modem firmware.  For most of us this isn�t a huge deal, but to iPhone 3G users who unlocked using the 06.15 UltraSnow unlock, and have been experiencing GPS issues, this is devastating�
For 3GS users experiencing problems, The Dev Team is definitely aware of the GPS issue, and currently working on a way to downgrade your baseband with iOS version 4.3.
