Sprint PCS announced two things this week that could really jump start the high-speed wireless data service on mobile phones in the US:
1)Sprint offers now for 10USD/month unlimited data transfer on wireless service plans.
This obviously helps adoption a great deal, nobody wants to count the Megabytes he or she is using.
2)Sprint and Sanyo announced that the very cool Sanyo 5300 will be on the market mid november. This slick phone as earlier reported sports a built in camera, 2 color screens and all other goodies and seems by far the best handset on the US market.

Sprint announces availability for mid November at 399USD suggested retail:
