I haven't used my PSP in awhile and want to start using it again. My current firmware is 1.50 and I would like to hear some expert opinions on what would be best. I don't have plans for buying PSP games at the store and would be interested in any apps that give the psp a more computer like GUI (iPhone style) or anything else I could enjoy out of upgrading to a certain firmware or what to do with 1.50. Thanks.
