FreedomPop, the service looking to disrupt the low end of the wireless industry with free service and low cost devices, apologized this week for delays in shipping its WiMax iPod touch cover. The cover, FreedomPop says, is caught up in the approval process at the Federal Communications Commission. To make it up to pre-orderers, the company is offering a FreedomPop Photon mobile hotspot with 2GB of free data, as well as the possibility of a free sleeve.
