Guest dambox Posted July 18, 2005 Report Posted July 18, 2005 Hi I have a c500 that is unlocked with a vodaphone contract SIM. I followed the upgrade instructions and all went well. However when phone reboots I constantly get a "data crash contact service provider" message. If I click keypad I can see the screen underneath - however it is unusable. I managed to down grade- seems it does not like the vodaphone sim - can anyone help out ? David
