So iMessage sends the message to two ios5 devices over 3G/Wifi, right? What if, for instance, my girlfriend is in an area of bad coverage for the night but I have 3G coverage. When I send an iMessage "text" how will she get it? She won't until she gets 3G or wifi coverage, right? That seems like a loophole. If I need to get in touch with her over text, I shouldn't have to manually disable iMessage just to send her an SMS.
