New iOS 5.0.1 Build Was Released to Fix 'No SIM Card' Errors?

The new iOS 5.0.1 build released yesterday may have been seeded to fix 'No SIM Card' errors on the iPhone 4S, according to MacRumors.

Based on a new Apple support document, it now appears that the updated build may have been designed to address an issue some users have been experiencing with SIM card-related errors. With the update affecting a relatively small portion of users, Apple may have elected not to push it out to all users in the form of an iOS 5.0.2 software update, and instead rely on those users who are having problems following Apple's advice and obtaining the new build through the restore process outlined as a solution for the issue.

In the support document Apple says that in certain situations, iPhone 4S may have difficulty recognizing a micro-SIM card, resulting in the following behaviors:
● "Invalid SIM" or "No SIM Card installed" alert appears intermittently.
● Status bar displays "No Service" or "Searching" in a location with good network coverage.

To resolve the issue, users are advised to restore their devices through iTunes which would install the new build 9A406 of iOS 5.0.1.

There have also been early reports that the new build improves battery life for some users.

Problems that have not been fixed (or mentioned) since 3.1.2: iPod/Music: If lyrics are displayed while listening to a song, there is no way to access the repeat, genius, shuffle, 30s, 2x  buttons since they become partially hidden by the lyrics. If one is listening to a book in 2x and uses Voice Control, dismisses an alarm or receives a phone call,  listening is resumed at 1x but the icon still indicates 2x

Don't download this 5.0.1 revised as it was patched to block any future JB stick wit the older version 5.0.1
