Access Issue

I have been unable to access BB&B from my iPhone when using cellular data for several weeks.

The site almost never loads. It works okay when connected to wi-fi, but that's not always available. I've cleared all my cookies and data, reset several settings, disabled everything to make my iPhone the most unsecured iPhone in the world, and I still can't access BB&B. It doesn't matter if I try to use the mobile site or full website.

The screenshots at the bottom are as good as I can get (sometimes the white screen is black).

I fully accept it's probably just me and something I'm doing, or even the crappy Verizon network around Boston, though it didn't really work in Fort Worth or DC either.
