Well for the iPhone You can choose not to get a data plan, and just use home wifi to download/play games. So you can use an iPhone as an iTouch with texting and calling.
Yea but lets say a person gives me the iPhone 4S so I can use home wifi and play it without taking it to AT&T and turning it on?
Nah I rather have something smaller and as long as I can play ravensword 2 and TWEWY and a few more I would be happy oh and bastion. Heck got the games from the sales and few gifted just need the phone but with out the big payments.
