Updated my iPad 2 to iOS5 and everything is good, except iMessage. When Im trying to send iMessage to any email or phone , it doesnt let me click on SEND button. Also, few guys tried sending me iMessages from their iOS devices , but I dint receive any. In went to settings. Confused about it. See the screenshots : http://d.pr/GNTL and http://d.pr/Q3b3 Why is it showing error ? And when I tried adding another email, it said, wrong ID and there is no option to delete email ? WTF ???? Another question. How does it work ? Is it only iOS to iOS devices ? How would we know, who has iOS device , while sending message ?
