If i were you, i wud have gone for the 6630 wid my eyes closed..its one of the best symbians in tht price range and easily beats the 7610,3230 etc. as it has hot swap memory,a faster processor and stereo sound.. none of which are available in the siblings...
Also the P990 costs almost double...though have to agree tht it has better cam,
umts,wifi none of which is thr in the 6630..:no:
