iPhone 4 with weak/no reception after being dropped. Re-seating the antenna connector didn't fix it.

The repair was quick and painless. I had previously installed the iFixIt iPhone liberation kit to replace the pentalobe screws with Phillips screws as well.

Be sure to keep your screws sorted out. I stuck them to an upside down strip of masking tape on a piece of paper, and noted where each one came from next to it.
