just disable them, then restart your phone...enable them. should work.

Three suggestions:

1. Are you running hideuseragent if so turn it off.
2. If you have fMMS installed, check what connection is being used whilst you update because I had the problem it kept defaulting to the MMS connection which gave me the same error you are having.
3. You are a helmet and dont deserve this device so place it in the nearest bin and forget about the problem.

Also, your thread title might get into the Guinness Book of Records for the longest ever thread title. Normal practice is to put more text in the top post than in the name of the thread.
