Cell phone renewal soon

Hubby can renew his contract in a few months and get get a new phone. We are trying to figure out which one to go with. Do we go with a smart phone like a samsung htc, or do we go with the basic cheapy one (that has a qwerty keyboard), that has the option of buy one get one free, so we can add Trent to our plan? More than likely it will be the latter, as I am too cheap.

I would love to have an iPhone, but do I really need to have the option of internet on my phone?!?!
