I just bought a brand new 6630. Could you all please suggest some good applications/games which I can purchase ? Also I want to know any good tools for increasing the phone's productivity like memory doubler or any such thing like we have for a PC.
I came to know from this forum of some MP3 players like Oggplayer / Ultra MP3. What are their advantages over Realplayer that comes bundled with the phone ?
Also is there any way to compress MP3 in some other format and still retain their sound quality to be played by Realplayer / any other player ?
OggPlayer supports play lists and more formats that Real Player.
Use Music Manager (part of PC Suite - latest version) to copy music to your device. It will optimise it for mobile use - convert and copy over for you).
Aside from that it really depends what you are after - there is a loott of good software about.
Try the freeware article on this site for some good free stuff.
Other than that I like Epocware's program. Infinite Dreams do some nice games as do ZingMagic.
