For some reason though, the Model # under the battery says 5160i but i searched for that model and it isnt even listed in Nokia's database... but the 5165 model is identical so i figured this is it.

This phone style had many model #'s depending on which carrier it was on. Nokia 5160, 5160i, 5165 were the few that AT&T carried. For it's day this was a great phone. Don't knock it, back then ...
