iPhone OS 2.1: Bugs and Fixes
Posted 3 October 2008 @ 5am in Troubleshooting
A few lingering bugs are posing issues for users of iPhone OS 2.1. Fortunately, fixes are readily available.
iPhone Declares Voicemail Password Incorrect This is an annoying bug that pops up now and again for many iPhone users. The phone will suddenly prompt the user with the message “Password Incorrect - Enter Voicemail password” while a phone call is being made. The iPhone will continue to nag you until you correct the problem. The easiest solution to this problem is to Dial 611 on your phone. After verifying your number select the option for help with voicemail and then the option for resetting your voicemail password. Follow the prompts from there to resolve this issue.
Caller ID Settings Some users are reporting a bugs in which the Caller ID toggle switch fails to work. This issue can generally be resolved by resetting the iPhone; hold the home and sleep buttons until the Apple logo appears, then release both buttons.

Has anybody else had problems with audiobooks in the iPhone iPod?
My iPhone frequently skips back a few minutes when I have paused listening. The skipping occurs usually, when the iPhone goes to sleep or the listening is interrupted by a phone call. It seems that the iPod resumes playback from the last “saved” position, meaning that sometimes the current position is not saved and thus next resume will start from a wrong point.
Oh, I listen to audiobooks in Faster mode, which might have something to do with the problem, and why there aren’t any reports of the behavior elsewhere.

one “bug” i have noticed is that the audio quality of the voicemails left in visual voicemail sounds considerably more compressed than it did in the 1.x software. before while the quality wasnt super crisp it was fine, now it sounds like the audio quality of a bad digital answering machine. is it just me?
