Nokia 6600 restarts

I was surfing the web and my n6600 was on the table charging .. all the sudden i see the nokia logo (the one that appears when switching the phone on) and i was asked for my pin code, my phone just retarted??... strange ? maybe it restarts whenever a new year comes ? __________________ no, that's probably just a crash, it's a new model so some bugs are still there waiting to be fixed, just visit nokia point sometimes for upgrading your mobile phone
