Hey guys - there's a much needed tweak someone should make. You should make it so that group messaging ONLY works when all recipients have iMessage, and is turned off when you're texting a group with 1 or more non-iphone users in it. I can't have it turned on, as then people without iMessage get confused/all the other senders' texts. But it sucks, as I can't communicate in the conversations that my friends have with iMessage. Would it be hard to create such a tweak?
