WARNING YOU DO THIS AT YOUR OWN RISK! PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.
1. There is no way to come back down from 06.15, and theres no hiding the baseband version from Apple. Youll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you wont be able to update to it if it remains down in the 05.xx sequence (then again, you wouldnt update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you wont ever be able to restore to stock firmware (it will fail). Youll need to only restore to custom IPSWs (then again, if youre unlocker you should already be doing that).
Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume youll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks dont work).
Certainly dont update to 06.15 if you dont need to! Only do this if you need the unlock and youre stuck on 05.14 or 05.15, and youre willing to assume the above risks.
