I am using the 8100 from TMO and I have updated my software to the new OS for the 2gb micro sd card. however, ever since I was not able to get the 1gb card to work when I inster it into my Pearl. It gives me a blank white screen and doesn't do anything. Any ideas? Is the new OS update bakwards compatible. Any assistance would be much apprciated.
