If your phone is within one year of purchase you will have an replacement as it is under warranty. If not you need to buy it for 2-4 centsw in any telephone shop who sell your model.Replacement under warranty can be obtained from any nearest dealer by producing your warranty card or bill of purchase..This is an common problem in this model..

At&T would replace that for you I priced it at $9 plus shipping. Trust me a while back i had mine replaced .. not the same model but still.

If they used the excuse that we do not have that part you might search ebay for that.. Otherwise a modification could be used until another phone can replace it.

I would give them a call.

Thanks and please click the accept button for my efforts.
