what is yr problem with the phone?

after send via bluetooth, go file manager > E:MAss Memory > Recieved files
all the file u recieve from bluetooth will be there.

aduhzz...if u can see files are there, that mean adi save in ur phone le la. u can cut and paste it to any folder u like.
PJP is a kind of overclock software tat boost up ur phone performance. worth to try it, and i am using.
i dun think that u can update ur FW through nokia software updater. bocs its temporary unavailable (for my case).

try using softwares like mykeylock, slideunlock or nunlock to reduce the dependency on the side keylock button
