everything there is to know about Pantech's slip-sliding Matrix PRO, but those two most important tidbits have thus far eluded us. Thankfully, the pricing and availability details you've been craving since last week have finally arrived. The handset will be available on the 24th (that's tomorrow, kids) in a steel-blue metallic finish at AT&T company-owned stores and online at the carrier's website. The pain? $179.99 after a two-year service agreement and a $50 mail-in rebate.
