Hi there.
Not a long time ago I bought an used N71 and it seemed to work ok for some time. But not long ago it started auto-restarting during phone calls. Once it rebooted even in idle. I gave it a hard format (3+*+etc..)-it didn't work. Reinstalling the firmware by PCSuite didn't help either. So I'm just asking-am I right if I'm thinking, that the only thing to do with it is to take it to service?
