Just some info for those that care. I just got a new PSP and did the CFW thing and proceeded to buy an official Sandisk micro sdhc card to use on my PSP. The reason I did this was because I shopping on ebay for a Sony Pro duo card and alot of sellers were selling these adapters so that you can use a micro sd card in your psp....I bought one along with an 8 gb micro card and I was able to save about 30 dollars over buying an 8 gb sandisk pro duo card. Upon receipt, I verified that it was a legitimate 8 gb card (ran some tests and wrote almost 8 gigs of photo files to the card without a problem) and proceeded to upload some of my games to it. Lo and behold, most of the games kept freezing after the initial intro screens. I thought it was the CFW but after I bought another Original Sandisk pro duo card, confirmed that it was the micro sd card. I guess the psp doesn't work well with it. Maybe others had good experiences with it, but I didn't. I wish someone had posted a warning about micro sd cards, but maybe I'm the first to have tried it. (Maybe I just didn't look hard enough in the forums) Maybe I just had bad luck, but maybe someone else can post a reply to this about their good luck or bad luck about it so others can avoid this mistake. It just ain't worth saving 20-30 dollars, especially since I had to go out and buy another card anyway. Hope some of you find this info useful.
