PSP Update 5.51 - Sony Computer Entertainment has announce that update 5.51 was put online for its PSP console. Nothing much to say about this update, according to them it improve only the stability of the system console during the use of certain applications or games. That's all ! Indeed, it is said that Sony found some bugs which had not touched the PSP players too much. I have heard , this update allows only the PSP-3000 16/9 to enjoy a greater general stability... Have a nice day!
