You can actually use any size, if you handle all writings and savings to the card in a memory card reader connected to a computer.

All Ericsson phones can READ all cards, but not carry out all commands made within the phone, if the commands involved altering anything on the card.

We have used 16GB in K610, but only for READING from the card.
