So I have the IOS 5 now on my iPhone 4 and I cant get this iMessage to work. I assumed from the presentation about it that it would automatically switch to iMessage when you go to text someone's number that has IOS 5 updated. Not me manually getting their apple ID email and doing it that way. Seems like a lot of hassle and it def. wasnt like that in the presentation. Do I need to freaking cave in an update to the iPhone 4S to actually have this work properly? So annoying right now. Not working the way they presented it.
