The constant oneupsmanship, to use a semi-real word, between Sprint and Verizon Wireless just got more interesting with the upcoming Sprint release of a Rev. A EVDO card. EVDO Rev. A is faster than the EVDO (Rev. 0) currently being used by Verizon Wireless, with download speeds up to 3.1Mbps and upload speeds of up to 1.8Mbps. EVDO is the wireless broadband network used by mobile phones in case you've been living under a roc...you get it.
The Rev. A card is backwards compatible with Rev. 0 networks, just don't expect to reach the same high speeds. The card should cost $99.99 with a two-year contract with Sprint; the price jumps to $174.99 if you're only willing to commit one year of your life to Sprint.
UPDATE: Quick correction on EVDO Rev. A's speed: according to Sprint's press release, the average download speed should be around 450-800kbps while average uploads will come in at 300-400kbps. These are average speeds and not theoretical maxima.
