I recently went from my B.B. back to a Samsung SCH-A970. I tried to use my 4 GB Micro SD Card, but the guy at the Verizon Store said it was "Too Big" for my Samsung to recognize it. I'd like to use the biggest SD Card I can for this phone. The guy at the Verizon store said I could go with eaither a 1GB or 2 GB Micro SD Card.
