Sony Ericsson

does anyone have any specifics and its memory card? what memory cards does it accept? im already assuming that it does not accept memory stick PRO duo unless theres some specific mem card formatting specifically for use with the fone. i have tried both 128 mb and 1 gb memory stick PRO duos. at first i thought it was because it tried the 1 gb stick first, figured, maybe it just not capable of goin that big, but 128 mb isn that big? anyways.... blah, blah, blah... the rest is not important, if anyone have any info on memory stick specifics with this fone, i would greatly appreciate it... this sucks only bein able to carry 16 songs!
