i used both of them before for a short period. the only reason why i dump them is because , one of the reason is , I cant SMS using those big hp one hand. Have to use both hands.
Ngage and QD is very nice if you are hard core gamers. But dunno why latest Nokia hp are sucks on ringing tones.What I mean is they before more softer these days even if you put on maximum level. I still miss my old Samsung hp but once you use Symbian hp like Ngage there will be no turning back. Lots of 3rd party sofware can be dumped into your hp.And yeah, get a bigger memory card. 256mb MMC card should do the trick.
I alwyas download some symbian software here:

You may also find some symbian software from ~you know where la~ RM5 only ma for one cd.
Alternatively, you may download some from Kazaa or Limewire.
And change the original hands free. It sucks big time. Made in ROC I think. If possible get 6510 ORIGINAL NOKIA hands free. It rocks. White color.
Remember, QD is a symbian hp, which means lots of things can be done on it. As long you expand the memory plus get the right software for your hp. And yes, it is kinda lag a little bit and sometimes it hangs. I think it is because it has small amount of RAMS
try looking at

Good luck in your hunting!
