Select Sound and Hold all screwed up...

[Cloud]

um yea...i dropped it in a river before :/ and the sound mutes it self all the time and the select button it broke. wierd but when i put it on hold it works the same as pressing the select button. like when im typing something on the psp, ya know how u can press select to have a different way of typing? well it just rapidly switches between them nonstop. would breaking into it and doing something help???
