Samsung Exclaim M550
HUGE screen and great features
Worried about a dual slide? This same hardware for the slide has been used in European conutries for the past 6-9 months and has proven to be reliable.
The keys are spaced out for easy texting, there is a Facebook mobile app pre installed on it, and YouTube looks AMAZING from this device with the larger screen. Battery life is the longest of any phone Sprint has carried.
If you don't mind the size, I say go for it.
