Apple has released the 2.0.1 Firmware update for both iPhone and iPod Touch tonight. Only "bug fixes" are listed amongst the release notes, but there has been some concern about the relative instability of the 2.0 firmware which was released on July 11th.
Several readers have noted general application instability requiring rebooting of their iPhones. While some of these findings may be application-specific, there are other scenarios that appear to affect the entire iPhone.
We hope that the 2.0.1 update will help provide some added stability to the iPhone OS.
