I recently purchased the HTC Inspire 4G off Ebay. When I received the phone I think it is rooted, I have no idea about roots or anything of the sort. The seller didn't say it was rooted only said it was unlocked. Here is my issue, the phone turns on and runs perfectly fine when the Straight Talk Sim card is NOT in the phone. When the sim card is in the phone, it turns on, and lets me unlock the screen, then turns black and shuts right off. I noticed in the phones settings it says "Advanced Tweaks". Can anyone help me get this phone working with my new ST Sim card? It does this to other Sim cards as well.
