You can now use the iPhone for free, as long as you don't mind old gear

To date, FreedomPop's no-cost phone service has been attached to older Android phones. That's fine for many, but not exactly diverse. Your choices are a little better now that carrier has added iPhone support to its lineup, though. You can get 200 voice minutes, 500 messages and 500MB of data per month on Apple's handset without paying a dime; it costs the equivalent of $5 per month if you need unlimited calls and texting. It sounds great, so what's the catch?

As you might suspect, device selection is the big gotcha. Much like Ting, FreedomPop isn't carrying the latest Apple technology. You'll have to be happy with either buying a refurbished iPhone 5 for $349 or bringing over a Sprint-ready iPhone 4, 4S or 5 you already own. This isn't the choice for those who want to live on the bleeding edge, then. Still, it does give you free LTE phone data -- a major advantage when the only alternative on FreedomPop with similar speeds is a hotspot.
