Apple has finally rolled out official firmware updates for both the iPhone and iPod Touch. Users can now update both gadgets to firmware 2..

The iPhone firmware 2.0 can be downloaded through iTunes 7.7. Mac Rumors notes that this release carries the same build number as the earlier leaked firmware 2.0 which has already been subsequently jailbroken.

A word of warning, though: Mac Rumors cautions users to avoid upgrading until Apple resolves all issues concerning server activation. Says Mac Rumors, "If you do upgrade and are unable to connect to the iTunes servers, your iPhone will be left in an unusable state".

The firmware update for the iPod Touch, meanwhile, is also available on iTunes for US$ 9.95. This update includes App Store support as well as various enhancements for Mail, Contact and Calendars. For the mathematically-inclined, a scientific calculator has also been added along with MobileMe and Microsoft Exchange Active Sync support.
