Sprint hasnt had a cloud storage service to counter offerings from ATT and Verizon, but its catching up quickly through a new deal with Pogoplug. The partnership makes it easier for Sprint customers to grab the Pogoplug app, giving them a fast track to 5GB of free online storage. They also wont have to jump through hoops if they need more space — they can now pay for Pogoplugs $5 unlimited plan through their phone bills.
