I bent the pins on the main board up last time I had the cover off to give me a better connection to the GSM antenna module (the one located on the far side from the camera) however the receiving contacts were quite worn. I lack the capabilities to re-plate them with gold but a small lump of lead based solder should let me guarantee that I am getting a good connection to the antenna.

I will let you know how I go. Was this issue giving you similar syslog errors?

I think one of the issues here is that a wide range of problems will give you this very common error. I plan to keep going through them till I find the right one.
