Users are experiencing some issues with installing the new iPhone 1.0.1 software/firmware release. Problems are most likely to occur if you made some type of modification to the device's software through the use of Jailbreak or other hacking methods.
In most cases, simply restoring the iPhone will allow proper installation of the 1.0.1 update. To perform a restore, Connect your iPhone to your Mac or PC and, 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.
Failing that, perform an "Erase and Install" as follows: go to the Settings application, tap General then select the Erase All Content and Settings. This will delete all media and data on the iPhone, as well as recent calls, etc., and all other settings. If you perform this operation and stop experiencing crashes, you might have problematic data being synchronized to the iPhone that is automatically put back when the phone is restored. In this case, you might want to go to iTunes, select Preferences from the File menu, then iPhone and delete your backed up iPhone settings â?? this includes text messages, notes, call history, contact favorites, sound settings, widget settings.
Some typical problem reports:
iPhone Atlas reader George Wilde writes:
"I had numerous difficulties updating my iPhone to version 1.0.1. It started when iTunes began 'verifying existing iPhone software.' Midway through I got an error that said "iPhone could not be updated. An unknown error occurred (0XE8000029)". The iPhone was then dead and could not be successfully rebooted. I was able to attempt a Restore after several attempts only to get the error 'The iPod (iPhone) could not be restored. An unknown error occurred -50.' After several more attempts I was able to get iTunes to successfully download and restore the version 1.0.1 Restore package (around 90 MB of download). iTunes then reactivated my AT&T account from the previous backup it made of my iPhone, and then resynchronized the address book, bookmarks, etc and redownloaded my music, videos, and photos. So my iPhone is now restored and resynched, although I did have difficulty resynching my mail accounts. Also none of my Wi-Fi account settings or Phone favorites or custom iPhone settings and other preferences had been saved by iTunes in its backup of my iPhone. That makes the restore process very long and unpleasant."
Mark Weaver adds:
"The update failed on my iPhone, I had to restore. I'm guessing this is because I had used current hacks to install ringtones."
Other issues solved?
We've yet to hear reports of other problems potentially solved by this release, particularly with regard to low volume, echoing and overall stability. If you have feedback on one or more of these fronts, please let us know.
