Thanks, that's what I needed! I decided that I will try to disassemble the phone before taking it to service (if it is just an alignment problem maybe I can fix it). I have a couple questions about: 1. If I disassemble the phone I lose my warranty? 2. In the L1 & L2 service manual, it says that the screws must not be reused, but I have none other .. whether I use it again is a problem? 3. If the GPS chip is dead, and I'm obliged to bring it in service point, I must pay for repair it?!
