Is there any way to.... Often I am out of range of a cell signal (or wifi) and think of something that needs to go out. I'd like to compose a message and set it to go off, as soon as a signal is acquired without further intervention on my part. Right now, imessage will fail the message after 10 minutes (I will lose interest and not watch the progress bar) and I often don't notice it failed. (so, a day later I learn important info was not shared) With email, it will go to the outbox and I similarly won't notice it didn't go; it will sit in Outbox forever with no notification that I um, notice. Any ideas?
