If you're like me, spending the past few weeks waiting for this device to be launched by T-Mobile, you can now celebrate. T-Mobile has launched the Dash for USD199 after an instant discount and rebate.
Also for Developers you're able to purchase one for up to USD300 discount. That makes the device just USD99! What an offer. Here's the link to the T-Mobile Premiere program.
So if you're a Windows Mobile developer, run quickly to a T-Mobile store or the links above to get one for your testing needs.
