What you are looking at, is info that shows us what phones are due out, and what some of the main features the phones will have.
We have covered the Samsung T629, T619, and T519, T719 and the Sidekick 3 before, but the newest addition that this pic has is the Blackberry 8705G (HAC). This is the same phone as the currently being sold BB 8700G, but this is a Hearing Aid Compatible device.
It also looks like alot of phone will be release in the 2 weeks. The only phone that looks to be released real soon is the Samsung T519, which is set to be released on Monday, September 11th. The Samsung T629, Blackberry 8705G (HAC), and Samsung T619 will all be released to the public on Monday, September 18th. Again, these are tentative dates. I call it tentative because since those dates are atleast 2 weeks away, T-Mobile can still delay, or either cancel the phones from coming out altogether.
T-Mobile has put the Samsung T719 on their website as "Coming Soon". When you go to compare their phone and choose the t719, it shows a price of $299 when you choose to sign up for a 2-year contract.
