Update is said to fix proximity sensor issues
Apple has reportedly seeded its second iOS 4.1 beta to developers. The update was distributed as five unique variants for the iPhone 4, iPhone 3GS, iPhone 3G, 3rd-generation iPod touch, and 2nd-generation iPod touch.
Although full details of changes in v4.1 have yet to be fully disclosed, the update is expected to address the proximity sensor issues that have affected the iPhone 4. CEO Steve Jobs recently promised a software fix for the problem.
