Hi all, Sorry, I am almost a complete newbie here but I was wondering if someone can offer some help with a really odd iMessage issue. The issue that iMessages are not working, in one direction, solely between two particular iPhones - I cannot send them to my girlfriend's phone. Basically: I do receive iMessages from her phone I can successfully send iMessages to any other iPhone She can successfully receive iMessages from any other iPhone We have tried with both phones side by side in front of us - I instantly get a "delivered" note next to the message, but they simply don't turn up - however long we wait. I can send SMS messages and calls to her phone, so my number isn't blocked (Just pre-empting the jokey answers - as above, we've checked the number isn't blocked and we've checked it with both phones there, so yes I'm sure she isn't just ignoring me ) Any advice gratefully received! Thanks!
