Back in Feb., we attended the HP Mobility Summit where we had a chance to see and play with the then called "HP Mobile Messenger". There has been lots of rumors flying around the net and even some hands-on reports, but we tried to stay away from rumors. But very recently, the HP UK site accidently leaked the info on the upcoming device which seems to be scheduled for release in Jan. 2006 in UK. The latest rumors are however for the US market, we might see it as early as August 17th, 2005 from Cingular.
Here are our HP Mobility Summit report and the hw6715 specs reported on Cnet (HP UK has since removed the product from their web site).
