Problems with Exchange, power, more
Downloaders of the iPhone 3.1 firmware are experiencing a variety of problems, according to talk on Apple's support forums. Perhaps the most serious involves occasional total shutdowns, which occur without warning. Affected iPhones can be revived, but only after a manual reboot.
Others have complained that the update hurts battery life. In one incident a person reports that a phone went from 100 percent to 55 percent charge in the space of six hours, despite being completely inactive and even having Wi-Fi and Bluetooth disabled.
Still more users are complaining of podcasts showing up in random order, instead of by date. More critical is a problem with syncing Exchange e-mail. It is believed though that the errors stem from server-side encryption options being properly enforced, as a result locking out the 2G iPhone, the iPhone 3G and possibly the iPod touch. The iPhone 3GS has built-in support for processing the encryption, and so should be unaffected.
