As we supposed earlier , T-Mobile has just started offering the new Samsung T729 Blast.
The Blast is a quad-band GSM/EDGE slider handset equipped with a SureType-style QWERTY keyboard, 1.3Mpix camera, Stereo Bluetooth, MicroSD card slot and integrated media player. This messaging-focused device comes with an email client supporting Yahoo! and Gmail, as well as POP and IMAP accounts.
The price for the phone is $100 with a 2-year service agreement.
