Well, nothing much to say about the features that has been explained in the other reviews in MS for this product.The Cyber-shot is very good and picture quality is nice.The audio quality is too good, especially if you listen with Sony earphones.The only thing that disappoints is their software. Not just for C510, but for any Sony Ericsson mobile. The software gets stuck more than Microsoft word / excel..!!
Sometimes, you press the call button and for a while the calling details dont appear on screen, while the other party is already shouting hello" from the other side. Even after you disconnect the call, the screen shows as the call is still on. But this software problem is not going to bother much, as this is on occasions and not at all times,
Note: I liked the Sudoku game that comes along with this phone, and thats a good time pass during travels.
