Memory Stick for PSP

[sevi]

Hey Guys, just wondering if anyone knows if there is a limit to the capacity of memory stick the PSP will accept. I'm looking at purchasing a 4GB stick for my PSP but wont bother if the PSP wont read it. Not sure if the PSP has a max of 2GB or something like that.
Any help would be much appreciated. Cheers.

on the older firmware the limit is 4gb i think at 3.00 the limit was raised

some people are using 8gb mem card without any problems. sony has not long released a 16gb mem card. so the same question could be asked for that card.
