I have a secondhand HTC mytouch that a friend gave me, I've had it almost a year now and it's still collecting dust. Keep meaning to take it to a T-mobile shop and see if I can get a simcard in it and get it up on the wifi (I don't wants no phone plan! I just want an android minitablet!).

Is it generally true that devices with GPS can use it even without network? (at this point I don't even know if that device has GPS tho)
