Late Tuesday, Apple released iPhone Update 1.0.2, the second major firmware update for its popular iPhone handset.

The new software, which can be downloaded by connecting the iPhone to your Mac or PC, selecting the iPhone in iTunes and clicking the "Update" button, is a 3.7 megabyte download and applies the following cryptic changes according to Apple: “this version of the software includes bug fixes and supersedes all previous versions.”

According to iPhone Atlas, the update erases hacks, forcing the code into a recovery and then restoration mode, thereby removing non-Apple-sanction modifications as well as third-party installed applications.

This feat is accomplished via a validation process performed on the iPhone. If the validation fails, the iPhone then moves into recovery and restoration mode, prompting iTunes to download a 92 megabyte version of the 1.0.2 software update to bring the iPhone in line with the current software revision.

Albeit Apple has been vague about specific fixes, some iPhone Atlas readers have reported a significantly louder maximum volume on the device. Other users have reported that the iPhone version of Safari (or MobileSafari) now smoothly scrolls pages as they're loading, where before scrolling on a still-loading page had been jerky or nonexistent.

Reports are still coming in and if you guys have tried the new update and seen any changes whatsoever, let us know in the comments or forums.
