Apple has released new iPhone 2.1 software on its iTunes online service that offers to decrease dropped calls, improve the battery life, improve e-mail reliability, improve text messaging notification, reduce 3rd-party application crashes and reduce the time it takes to sync the device with a computer. Users have noticed more "bars" on the connection meter and have reported that it was faster performing key tasks. Last month"s update from Apple drew some criticism from users that claimed that it did not enhance access to high-speed data networks as Apple had predicted. In this update, Apple also patched 8 security vulnerabilities including the "passcode bug" they fixed last January but failed to include in the July iPhone 2.0 update. The other 7 vulnerabilities were the same 7 that were fixed in the iPod Touch 2.0 update earlier this week.
