Apple just announced software 2.1 for the iPhone. It promises fewer dropped calls, big battery improvement, no crashes with apps, and faster backups. The software update will be available September 12th and will be free.
If you own a first generation iPod touch you can upgrade to the 2.1 software that the second-generation iPod touch has. The software includes several new features including the new Genius playlist feature and includes a built-in Nike+iPod app for tracking a run using the built-in transceiver.
The software update is available today and is free for users of version 2 and $9.95 for iPod Touch owners upgrading from version 1.x software.
