is there such thing as a test screen on blackberrys?
to test and see all the hardware info
like on garmin when you press the up right screen for 10 sec it shows all the hardware info satellite info and all.
i want to see if my 8330 actually has a bad trackball sensor or its something else.
Try dialing ##000000 . Be sure to press the green button (or the enter button) to send the digits.
On some carrriers, you can dial #4357* to get to a different screen as well.
You can also perform several hardware tests by going to Options > Status and typing in TEST.
Also options > mobile network > press menu > Diagnostic Test
