Weird, I don't overclock my nitdroid at all, but have lots of random reboots. I'm only using a class 2 SD card but have class 10 at home, I just haven't had time to copy everything over to it yet. I hope it makes a positive difference. Amazon's new Android App Store works on nitdroid, and they are currently giving away Angry Birds Rio full version for free, that's where I installed it from.
