6670 or n-gage

ok i have a friend that wants to sale me a n-gage QD for 75 dollars with all the games he has, but i also been wanting to buy the 6670 of ebay for $350. Now I'm not sure if i should get the n-gage or stick to my orginal plans on getting the 6670, i've read you can downloads games on the 6670 like splinter cell and what not, is this true? I know for the n-gage you can go off and buy or download lots of games for free. They only thing i dont like about the n-gage is that you dont have a camera which i really wanted. And i like the 6670 cuz of the office stuff it has even if i'm just in a freshmen in college but it can help me in the long run. The phone i get now is the phone i'll be using for the next 2 years. please if anyone out there can help me make my mind up by helping me out with there past expriences i would really like that, thanks...........oh and i were getting a 6670 would it be best to just get a 7610, which are kinda the same but i know the 7610 is going be released in the u.s. by cingular and i wanted something no ones has...besides its going to take phone companies in america a long time to catch up with the outside modern world so i think 2 years with the 6670 and they still wont have that kind technology on basic phones in the u.s.
