Hi, new ipad mini is great except for trying to use the text messaging. 75% of the time I get the message send failure notice - yes, to fellow iMessage users. I have tried the power button and round button reset several times, turned off iMessage in Settings and turned it back on.... To no avail. I have wifi working, everything else works (email, Internet, etc.). When iMessage actually works is completely random... And most of the time it doesn't work at all... Also, texts messages sent from my iPhone4s will appear on my mini hours later... Most recently, the messages between my husband and I (sent via iPhone) completely mixed up when they later appeared on the Mini: my messages were in a block and his messages were in a block - rather than a back-and-forth conversation. Never seen that happen before - so any advice? I can't get to the Genius Bar because of sick kids so thought I'd start here. Thanks.
