Sony Ericsson K550 / W610

I got this phone as a gift for someone, and wnted to get a M2 stck, but the specs say it only supports up to 1 GB. My SOny Digital camera also claimed it only supported Memory Stick PRO Duo cards up to 2GB, but I popped a 4 GB one in it and it worked fine. Was curious if anyone tried a stick higher than 1GB in this phone before I waste money on a stick that wont work in the phone.
