hi every1, i juz got my piano black psp slim yesterday wif ver 3.90 m33-3, i asked for 4.01 m33-2, the seller told me it's not stable yet izzit true? and i'm not really happy that the new psp slim i got having some minor scratch near the memory stick bay there is no point to apply invisible shield on a scratch console. Gonna return it exchange it tomolo wif the seller, til then i cant play wif it. ><.
