Hello all I'm not really sure how iMessage was activated, but I have it turned off. And notification is also turned off yet my ISP, ( att) can override my settings and put a pop up on screen saying they sent me a text msg. This isn't a big problem but rather a small annoyance. Can you delete iMessage yet, or do I just live with it? Or if I can't delete it like you can an iCloud acc, maybe I'll start using it, it seems like a good feature.
