Did you have any issues with the 2GB card slowing your phone down? I just recently picked up a 6230 for dirt cheap, and didn't know it had a built in mp3 player until I went to install my SIM card and discovered the 32MB card MMC card that was already in it. I would like to get at least a 1GB card for it, but if a card of that capacity will cause my phone to be slow and sluggish, then maybe I will just pick up a 512MB mem card. Thanks in advance.
