Apple iPhone update 1.1.1 offers louder volume, adds iTunes

To download the 152MB update, iPhone owners need simply to connect their iPhones to their Mac or PC and click the "Check for update" option in iTunes.

One more warning:

"If you have modified your iPhone's software, applying this software update may result in your iPhone becoming permanently inoperable," Apple re-warned customers in the release notes accompanying the software download. "Making unauthorized modifications to the software on your iPhone violates the iPhone software license agreement, and the inability to use your iPhone due to unauthorized software modifications is not covered under your iPhone's warranty.

Version 1.1.1 of the iPhone software includes new features, bug fixes and supersedes all previous versions, the company added.

New features include:

Security updates

In addition to the unspecified bug fixes and documented new features, Apple also said the software update includes 10 individual security modifications. According to a detailed list of security related changes posted to the company's support site, seven target the iPhone's mobile version of Safari, two its mobile Mail client, and one its Bluetooth implementation.

Apple has also updated its iPhone website with a video demonstrating the new features, including the Wi-Fi iTunes Music Store, Ringtones, and more.

Update not third-party app friendly

Much to their dismay, several users of the AppleInsider forums who had installed third-party "hacks" or applications on their iPhone — but had not unlocked the device from AT&T's network — report that the software update reverts their handset back to its original intended form.

Update may delete Notes, Favorites

In addition, at least one user has experienced an issue where following the update all of his Notes and Favorites had been erased.

Update:

AppleInsider reader Will lets us know that another cool feature added to the iPhone with the 1.1.1. update is the ability to play MP3 audio files attached to mail. We tried it and it sure does work.
