Hey B, when you pulled the battery did you leave it out for a minute or put it right back in. when i first got my phone and i was setting it up the tech on the phone told me when i do a battery pull to wait about 1 minute before i put it back in or it may not do a full re-boot. but either way when you call sprint let us know what happened.
P.S. i still did not find out a fix for the DC in the messages folder yet i don't think there is a way with the new software update. but i did not give up i'm still trying.
