So last night I sent two friends a group text...they both told me they got it as a picture message (both on Sprint). I checked the message I sent, and at the top it says "Group MMS" and not "Group Text" like before... I checked in settings and didn't see anything that would change this. Is this maybe a bug in iOS 4? FYI, I'm running iOS 4 jailbroken on a 3Gs.
