It sucks because I'm an iPhone Developer and want to put on the 4.1b2 firmware on badly, since I hear it does fix the issue, not to mention the fact that AVRCP is finally implement for Bluetooth playback control.
However, installing the firmware makes it difficult for me to develop my existing applications on it, since the non-beta version of Xcode won't talk to the beta firmware properly, and if I installed the beta version of Xcode, I can't submit my apps to the App Store built with that SDK.
Ugh, I'd wish they'd just hurry up and release it already.
