With 8310's when they display Contact service most of the time it's a problem with one of the chips not a software fault.The only advise i'd give you is to take it to your local Nokia repair centre for either repair or exchange depending on the network your on.Otherwise speak to your network provider.
Hope this is some use

Problem is in the software
Flash your PPM and it will be ok.

before flashing
use nokia tools dct4 by techtron - u can find it here somewhere...

and follow instruction that are in that program for how to repair contact service...

if is not working - flash your phone with mcu same version...
