iPhone iOS 5 / iOS 4.2 Problem: How to Get Your Music Back

Some iPhone owners who jumped to install the iOS 4.2 firmware update yesterday were greeted with an unwelcome surprise. Media including music, audio books, podcasts and videos disappear after the update is complete. iTunes still displays the storage space occupied by the media files, but they are nowhere to be found on the iPhone.

Opening the iPod app simply says "No Content" and re-syncing with iTunes does not bring back the media library!

How can I put my iPhone in field test mode / check antenna signal strength in dB?

Field test mode is a special mode that changes the cellular signal strength bars on your iPhone into numbers for more accurate antenna signal measurement. To see signal strength in dB instead of bars follow these instructions:

1. Your iPhone must be running iOS 4.1. Upgrade if necessary.
2. Open the Phone app.
3. Dial *3001#12345#* on the Keypad and touch Call.
4. Your iPhone is now in field test mode.
5. To exit press the home button.

Smaller negative numbers indicate a weaker signal (for example -110 is worse than -50).

Lawsuits Mount as Apple Works on iPhone 4 Software Fix

Apple now claims an error in the iPhone 4 firmware is responsible for the dramatic drop in signal bars some have experienced when the device is held a certain way. An update for iOS 4 will be released in the coming weeks to address the problem, but in the meantime several lawsuits have been filed against Apple over the issue.

The most recent suit was filed Friday in the Northern District of California and accuses Apple of false advertising, breach of warranty, and unfair competition among other complaints. The plaintiff, Steve Tietze is seeking class action status for the case and contends that Apple is guilty of "misrepresenting and concealing material information in the marketing, advertising, sale, and servicing of its iPhone 4 - particularly as it relates to the quality of the mobile phone antenna and reception and related software."
