Well I have used both phones..

7710 is a S90 and not much software/games available for it.. but it is an very good phone and is touchscreen.. But then again i will really recommend it for business ppl.. anyone who is like me putting 100's of apps etc.. i didn have much option..

K750i on the other hand has an excellent camera.. and if u want camera and FM as the major usage then u should definetly go for this phone.. It is not a symbian and thus hardly any apps but u can put loads of java games in it..

Now look at ur usage.. and u can decide..
