In a move that’s sure to spark a new round of music video appearances, Sprint has just announced that they are rolling out their next-generation push-to-talk service QChat in an additional 40 markets. Amongst the new cities receiving the instant connection treatment are Austin, TX, Boston, MA, Chicago, IL, and many others. Additionally, Sprint made 4 new QChat-capable handsets available today to commemorate the event. You can now purchase the LG LX400 for $79.99, the Samsung Z400 for $99.00, as well as the Sanyo Pro 700 for $79.99 and the Sanyo Pro 200 for $49.99. As usual, nothing about these handsets is going to impress your executive board, but at least you can “wow” your friends with that lightening quick connection time, right?
