hey guys, i am in a bit of a pickle at the moment, my n900 was working perfect for the last 2 months and all of a sudden on Sunday it just decided to stop making phone calls, the simcard reception bars have dissapeared completely as have the service providers name! I tried searching for a network manually and its as if the phone cannot recognise the sim card. Tried a different sim card from a different network ant it wont recognise that either. I didnt update or install any software at the weekend so im lead to think this may be a hardware issue. Ay help would be greatly appreciated as its just a tablet p.c. at the moment.
