Contact issues linked to Google Sync downtime

Some serious issues have been affecting a portion of people upgrading devices to iOS 4, according to Apple's support forums. Perhaps the most vital involves cellular data, which some iPhone owners have reported as simply not working, whether on 3G or EDGE. The issue may be tied to carrier updates for iOS 4, but in any case some users are reporting that it may be necessary to reset settings, or even restore a device to a fresh state as opposed to a backup.

Some other iOS 4 users have been claiming that their contacts have completely disappeared. The problem may be comparatively simple to resolve, as it is believed to be linked to sync services in most cases. Google explains that Google Sync experienced "unplanned maintenance" on Monday afternoon, affecting the ability to link with mobile devices. Users say it may be possible to return contacts by simply leaving the Contacts app open for a while, or turning sync off and on again.

Several other potential glitches are said to to include push notifications or MMS no longer functioning, and auto-lock defaulting to one minute without the option of changing the timing. Some photos synced from iPhoto may turn out blurry. In extreme cases the iOS 4 update may fail, and cause a device to reboot continuously.
