Recently my N770 has been slowing down to the point of locking up. Can't be due to the software running, haven't changed that (or the OS) since the start of this year. And this even happens with Wireless off, Bluetooth of and only the clock running. Trying to access the clock leads to a lockdown

OS Version is the 2006 that enabled swapping to a SmartCard. I also got a larger (1GB) card in December 2006.

I have since tried to disabel swapping, deleted a rather large set of pictures and all. The funny thing is, some days it works fine, some it does not. The unit has no visibel damage, has never been sat upon or used as a throwing weight.

Any ideas? Since it is an early model the warrenty is IIRC up (2 years in Germany)
