hi,firsly im sorry if this thread might or may be in a wrong place.
i have installed some java games on my e51.but most of it,were very unstable or what we called laggy,specially when i turn on the game's sound.
i just wanna know if this is a usuall problem of e51.or there must be something wrong the way i update its firmware(410.xxx.xxx).
Lasty,sorry for my english
