While Samsung's SGH-X507 probably won't set too many hearts racing, it has just enough features to distinguish it from the usual crop of entry-level, free-with-plan phones. In addition to a fairly good external secondary display, the clamshell includes EDGE for data transfer, USB connectivity and Bluetooth. Seems like only yesterday features like this positioned a phone in the midrange category, so it's always nice to see more and more trickling down to the low-end. PhoneArena expects it to debut on Cingular for under $100.
