i can still send and receive imessages from the email addresses i've associated with it but i'd much rather send them from my mobile number so i don't confuse everyone.
i've been on the phone to apple care who've been in touch with vodafone about this, apparently it's a known issue.
has anyone else managed to get their ported number working with imessage? if so, how did you do it?
apple care are escalating this to their technical teem on monday.
