GB Wireless is highly recommended. The owner is very skilled and patient and can do micro-soldering. In fact other companies who have less skill often farm out the hard jobs to GB Wireless. GB wireless replaced my battery in 40″ while I waited which required soldering the battery in. When my charging port failed, GB Wireless worked on it on New Years Eve and although the job required more diagnosis than was possible that evening, the phone was ready soon after the store opened the day after New Years day. I drove from Takoma Park, MD to get my phone repaired by GB Wireless Cell Phone Computer Repair and my friend drives in from Accokeek, MD when he needs phone repair services. If you want to keep that old device running. GB Wireless is the place to do it!
