FreedomPop, a cellular internet service provider and maker of an iPod Touch case that can turn it into a full working smartphone, has just implemented a new "data rollover" feature for its plans, which let users keep unused data from month to month. The service, which offers 500MB of monthly WiMAX and LTE cellular data for free following the purchase of one of its custom sleeves for iPhones or iPod touch models, allows users to share data with friends and earn additional free data through referrals. It provides either mobile or home internet service.
