So I have iOS 5 beta 6 on my iPhone 4 & I of course use iMessage all the time. Well here's my problem. A lot of my friends have iOS 5 beta 4,5, & 6 on their iPhone 4. When I send texts to them I never get a " read " receipt, only a " delivered " receipt. But my friends that also have iOS 5 say that they always get a " read " receipt when texting me. Well recently I got one of my friends 3GS' up to ios 5 beta 6 & when I text her, it shows me the " read @ ( time ) " receipt, but she's the only one it works for. Can someone tell me if this is a bug, I'm missing something, or if there's anyway to fix this? Thanks in advance everyone.
