Major, minor iPhone 3.1 upgrade problems and how to fix them

Anyone having problem with there Iphone since the new update? Here are a few things you can try.

• Reset your iPhone by holding down the sleep and home buttons until the Apple logo appears.
• Restore your iPhone: In iTunes, click the Restore button under the Summary tab. Restoring the phone will erase contacts, calendars, photos, and other data on the phone, but will restore automatically backed-up information including text messages, notes, call history, contact favorites, sound settings, widget settings, etc. Of course, make sure that you back up your phone before restoring.

Podcasts are listed in random order for some users who are reportingthat podcast episodes are not being displayed properly by date. We encountered this problem in one out of seven podcasts on a test iPhone 3GS. This bug has been confirmed by Apple, so look for a fix in a future firmware update.

This has been happening to me a lot.

Random freezes or shutdowns are a major complaint for users after upgrading. The problem is the source of heated discussions within a huge Apple discussion threadcontaining nearly 900 posts. The problem seems to manifest itself whenever the iPhone goes to sleep, the user locks the display, or just randomly. When the user next tries to use the phone, he or she will find it completely unresponsive--the display remains blank and pressing buttons won't wake it. The only recourse for the user is to perform a reset as described above.

Battery life is another major complaintfor users after upgrading and one we've encountered ourselves. So far, none of the usual fixes have resolved a problem some are claiming happens even when the iPhone is idle. Regardless, we've noticed on our own iPhone 3GS that battery life is significantly poorer after upgrading to iPhone OS 3.1. It isn't unusual to commute home at the end of the day with 25 percent or less battery life.

Apple is clearly aware of the battery problem and is actively trying to resolve it by engaging iPhone users in a study. Participating users will receive a special BatteryLifeLogging.mobilecongfigfile that will capture Powerlog files from the iPhone when syncing with iTunes. The user sends the log files to Apple via e-mail or http://bugreport.apple.com. Hopefully with enough input, Apple will find the root cause of this problem and issue a fix in a future firmware update.

Slow or sluggish performance is a complaintfrom some users, blaming the problem on MobileMe syncing. 1. Launch the Settings App
2. Go to Mail, Contacts, Calendars
3.Go to your MobileMe account
4. Turn off contacts and calendars
5.When prompted, delete them from your iPhone
6.Reset your iPhone by holding down the sleep and home buttons until the Apple logo appears.
7. Perform steps 1-5, but this time turn contacts and calendar syncing on.

If the above steps do not resolve the problem, another alternative is to delete your MobileMe account from your iPhone, perform a reset, and set up your MobileMe account from scratch.

Unknown error (-50)was an error we encountered when syncing from iPhoto to our iPhone 3GS on another computer. According to Apple, all we needed to do was sync using iTunes 9, which we had not installed on the second computer. After upgrading to iTunes 9 the problem disappeared.
