Finally, it's out!
Firmware update 2.1 for the iPhone - the one expected to fix most major bugs in the iPhone and finally make it as it should have been at launch.

• Significantly better battery life for most users
• Dramatically reduced time to backup to iTunes
• Improved email reliability, notably fetching email from POP and Exchange accounts
• Faster installation of 3rd party applications
• Fixed bugs causing hangs and crashes for users with lots of third party applications
• Improved performance in text messaging
• Faster loading and searching of contacts
• Improved accuracy of the 3G signal strength display
• Repeat alert up to two additional times for incoming text messages

   Hold the power button at the top until the red slider appears and power it down completely.
