Well, it looks like Cricket will not be the only carrier to offer a pre-paid iPhone 4S / 4 in the US. Boost Mobile will also offer pre-paid iPhone 4 and 4S, reports TechnoBuffalo. According to TechnoBuffalo trusted source, Boost Mobile will carry both pre-paid iPhone 4S and iPhone 4 in early September. It’s unclear whether Boost Mobile will offer their $50 unlimited talk, text, and data plan or will they charge for ‘premium data’ like Sprint. That’s would be a good deal, as long as the data speed aren’t as horrible as Sprint currently data 3G speed.
