I have a 6670 with 1GB card but I am interested in buying a 2GB card, which apparently may or may not work depending on the brand and the firmware version.
If you have a 2GB on a 6670 or on a 7610, please reply with your phone's firmware version (press *#0000# on your phone) and the specifics of your 2GB card (brand, model, etc.).
Hopefully we can figure out how to get 2GB working on our phones!
