Is this what a post Steve Jobs Apple looks like? You would think in a closed-off world that Apple keeps iOS-based products in, that these sorts of issues just wouldn't happen, but here we are. Apple says that they are still investigating battery drain issues with the iPhone 4S after some users complained that the newly-released iOS 5.0.1 update didn't solve their issues.

Now Apple users are looking at more issues, such as microphone failures, Wi-Fi signal loss, and cellular network reception issues. Apple said in a statement to All Things Digital:

The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues.

iOS 5.0.1 only debuted roughly 24 hours ago, with Apple claiming it would fix the iPhone 4S battery drain issues. The update also introduced multitouch gestures for the original iPad as well as a few other new gems. While it fixes some users problems, other users said battery drain was bad, or worse than before.

Then we have the new problems with iOS 5.0.1, such as microphone failures, Wi-Fi signal loss and cellular network reception issues. The Startup Foundry reports that the update is forgetting to list contact names when the user receives a text message or call.
