Sprint has released a software update to their HTC-built Mogul smartphone which basically doubles the handset's data download speeds - and boosting upload speeds by nearly 8x - by enabling EV-DO Rev. A.  The update also enables GPS on the Mogul, which became one of my favorite Windows Mobile devices when I reviewed it last Summer.

This faster, badder, refreshed Mogul now becomes the first phone in the United States to work on an EV-DO Rev. A network, a land until now reserved for laptop modem cards.  In fact, it's laptop users taking advantage of Mogul's tethering capabilities who will probably get the most use from the Rev. A upgrade, as it really provides a noticeable boost during file uploads, including sending of Email messages with attachments.

You can get the details on the upgrade from Yahoo! News.  The software update should be available shortly on HTC's Mogul Support page.
