After much fanfare, the iPhone OS 4 beta gets out to developers ready to test out the new OS on their iPhone. Unfortunately, it seems that there are some problems with the firmware or the server at the back end.

Forums are filled with posts describing the errors they faced with new OS. One such developer express disgrunt that his multiple attempts to update to 4.0 weren’t successful. The itunes software always return error code 13 (which usually indicates bad USB cable or USB ports).

While some had success updating the firmware using the Mac, the PC users are left in the dark with strange upgrading issues.
