I dont understand something... the specs of the iphone 3GS is 600Mhz processor with 128mb of ram memory...and the PSP 3000 has a 333mhz processor with 64mb ram....if the iphone is more powerful why dont they make games as good as the PSP's?
Well for gaming get the PSP of course. Touch Screen gaming will not last as long as a PSP's game's would. PSP's are very fun but you need the right game's. If you get one make sure you get Resistance Retribution (My favorite handheld title ever) SOCOM FTB3, and Gran Turismo for a nice begginers kit type package. You have to get used to shooters on a PSP but once you do it's great. Although the Iphone is the Iphone so....If it's for gaming PSP, if you want a phone and mediocre games, Iphone. Dont get the Ipad, it is terrible....unfortunatly
