How dumb are you looking at? I wouldn't agree if you use IPT 5 with phone that can only make calls is a good idea. IPT5 is all about wifi so its practically useless on the go. Unless you have a phone as wifi hotspot so you can browse internet/appstore via IPT.
Chinese smartphone with Android should do it.
For $100, you could get a high-end quality Chinese smartphone.
With many features, and free shipping, of course! Could browse Internet and watch movies.
Or, you could save some money and buy a cheaper version, if you don't care much.
