As one of its daily deals, 1Sale offers the refurbished FreedomPop Sleeve Rocket 4G Mobile Hotspot Sleeve for iPod touch, bundled with 2GB of FreedomPop data and 500MB Bonus Data (2.5GB total), for $9.99 with free shipping. That's tied with last week's expired mention and $67 under the lowest total price we could find for a new unit elsewhere. It wraps around your iPod touch like any protective case, but it also allows your iPod to connect to the internet and be used as a hotspot. Deal ends today.
A 90-day warranty applies, although it's unclear who backs it. Note that this item is compatible with the 4th-gen iPod touch (30-pin dock connector). Expect this item to up to two weeks to ship.
