Thanks for starting this thread. My previous two-year agreement with Sprint is up come November and I have to decide what I'm going to do with a phone. I've been pretty stoked with my friends Droid X, but Sprint has always been good to me with customer service or anything I ever needed from them.
I am on my second Samsung Instinct, which was one of their first 3G phones they had. My first one was chewed up by a baby huskie. It's still an awesome phone, but doesn't have all the perks the new phone has. Hearing the thing about the battery sucks. My Instinct needed about one full charge a day to work, but I was able to save and hoard four batteries for it after replacing it the first time.
If you could let me know about how the camera works and takes pictures, that'd be awesome as well.
