So I just recently heard about the new "cupcake" update so I figured that I should probably get a memory card for my phone (didn't purchase one when I got my phone).. If I remember right the people at T-Mobile were trying to charge me like 50 some on dollars for a little memory card (something like 2GB or something?). So I went on eBay to try and find some and ran across a bunch of different kinds. g1 memory card, Cameras Photo, Cell Phones PDAs items on eBay.com has anyone ever purchased one of these cards before? or are currently using one of them? I want to buy one but am not sure which one would be the best. Any thoughts?
