So if I leave my phone in my pocket (specifically in my pocket...) for a long period of time (as in, if I'm at work) and then try to use it, it will have full coverage but absolutely no data until I do a soft-reset.
This is the only thing happening with my phone, and so far having to reset it is the only thing I know that fixes it :-/
