Problems with Group SMS I have an iPhone 4S. Whenever I try to send a group message to people who have iMessage and people who don't, I either get replies from 1 person but I recieve it as an individual text message or I don't get any replies at all. Everybody else in the group who has iMessage is able to see the replies as they would in any other group message. Please help!

*I have tried resetting it to the factory settings, turning iMessage and Group SMS off and then back on, and turning off my phone.
This sounds like a temporary issue. Can you reproduce it after updating the os and carrier settings?

Can you reproduce it after signing out and back in to iMessage with your appleid?
