when i first used my new ipod touch 4g, the accelerometer/gyroscope didn't seem to be working. i tried using gyroscope controls on MC2 but nothing happened when i moved the device. same with chopper 2. strangely doodle jump still worked. eventually the gyroscope started working again, but im just wondering whether this has happened to other people. should i bring it to the apple store or, now that it is working again, should i just continue using it normally? and speaking of the gyroscope, what were your first impressions if it? i used it with MC2 and while it was pretty cool, the sensor felt really sensitive and it made it harder to play. i will get used to it soon
