K850i funny Signal troubles!

Hei again folks,

my k850i recently had a keypad problem, the touch sensitive pads just stopped responding and i ended up spending $$$ replacing the whole keypad.

Anyhow now, the signal seems to be alittle crazy!
At times it shows no network access, no network, i would then have to off on the phone and somtimes even remove battery and try again.
Its alittle crazy, and would take doing those things several times sometimes before the signal is back up.

am i the only one having heapps amount of probs with the k850i ? or is the world suffering with me ????!!!!
