WARNING: updating to iPad baseband for iPhone unlock may disable your GPS

The iPhone Dev-Team has issued a notice stating that updating your iPhone to the iPad baseband for unlock could result in the loss of GPS functionality.

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 you’ll 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 don’t work).

Hackers are currently working to fix this.

As usual we remind all users - if you don't absolutely need to update your baseband, don't do it.
