A new Samsung phone will come to AT&T really soon. This new model will be the Samsung A657. Not official information about this phone but if you see the drawing, it has a weird look. Almost remind me the Samsung Matrix with the back of the T-Mobile SDA with the little handle on the top. The Samsung A657 will come with quadband GSM and Dual band UMTS 850 and 1900. Bluetooth and will support micro sd card.
Keep in touch for more information.
