my ps3 is doing the same thing now i was playing GTA4 and they kept doing glitches and at first i could play gta but then it kept on frezzing so i thought it was the game and then the ps3 wouldn't read the games so i stpped playing 4 a day and its doing the same thing the best thing to do call sony or ask gamestop if the fix systems or if they could see what the problem is

give your brother the ps3 so later on he cant say you never gave him anything and the ps3 by te summer will have alot of games and a great addition to the playstation network that will rival the xbox live. its called home... its like you have a sim and an aprtment and you can meet other people and arrange game sessions or join and you know how you on the 360 how you get rewards for doing something in the game well on the ps3 home when you get a reward you also get like stuff to add to the apartment you live in andmake it look nice and stuff plus the games for ps3 are not that bad... dont give it away cuz later on your gonna wish you had it for certain games at least give it to your brother so you can also play it
