sorry to sound fanboish, but is there any chance you can get hold of a iphone (locked or oherwise?)......at $400 for a 8 gb, that's thes best vfm as well as the most usable phne you can get
think k790i is in the 15k range...better than n73me in UI and cam pics...i dont own neither so cant say about stability...
n70 is a very good phone and is very stable, but isnt attractive these days.....w580 might be the attractiv alternative if u dont want a gud 3mp cam and music is a priority
edit:didnt read that u needed cam..k...w580 cam is good for its specs...u wont regret....however night mode sucks(but then it sucks in N73 as well)
