Hi. I had almost decided to buy 6630. However now that the new N70 is launched here (in India) I'm considering that. Could you please let me know the pros and cons of N70 over 6630 ?

Try the Nokia webiste and compare the 2 phones. Link below

Personally I would go for the N70, more advanced phone with better features and better camera. The N70 wins hands for me.
