having issues due to switching phones. my sim card was too large & a friend & i cut it down. But when my friend went to place it in slot, 1st problem, was still too long. Then he also had it upside down & backwards. i went to the phone store & got a replacement sim card. but still, no response to the new card. hoping its not the reader. i did start taking the phone apart by watching a utube video. now i cant get the screw by the camera out. what do i do? i am lost & stuck!! please someone help me!! please!!!!
