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?
