Just two days after seeding the first beta of iOS 5.0.1 to developers, Apple has already pushed out a second version for testing.
The new version, known as build 9A404, comes as Apple is working quickly to deploy the update to address battery life issues and bring several other enhancements to devices running iOS 5. The latest build is available as an over-the-air update for those with the first beta of iOS 5.0.1 installed on their devices.
