FLO TV had previously announced that it would ship a piggyback tuner for iPhone and iPod Touch in the first half of this year, then in late March said it would be ready within a month and a half, according to an article in TWICE. The same article reports that now the company says the Juice Pack TV is not far away.
The device adds a FLO TV tuner that allows you to receive the subscription-based mobile television service. The tuner actually retransmits the signal to your iPhone or iPod using WiFi, and up to three other devices can share the encrypted signal. The Juice Pack TV is made by Mophie, and also serves as a battery extender.
