You might take your phone in to have the radio checked too just to make sure its not your phone. Have them run post on it and that will tell then if it is your radio going out or if in fact its the network. If your phone is rooted it will still read, so they can't say no. its in policy that they have to work on rooted phones and if they can't fix it, they have to order you another one.
