Fire up the r-mill. An anonymous tipster has it that AT&T will launch the (dragon-scale green) Samsung A877 on March 29, 2009. According to PhoneDog, said A877 (possibly codenamed “Jackfrost”) is quite the non-smartphone (like the Samsung Memoir, it runs the smartphone-esque TouchWiz OS), and could be a solid replacement for the recently deadpooled Quickfire.

Rumored specs include:

• 3.2″ WQVGA AMOLED touchscreen
• Slide-out QWERTY w/ messaging shortcut button
• 3 MP camera with geotagging
• Telenav GPS Navigator
• Full HTML browser
• TouchWiz user interface
• Quadband EDGE/GSM
• Dual band HSDPA (1900 and 850)
• Bluetooth
• MP3 player
