I've been complaining about the coverage of AT&T Wireless for three years, since the day I switched from Verizon. My iPhone doesn't work where I need it most: at home, on top of the Hoan Bridge, on vacation in Door County or at the cabin Up North.

But where I'm most bothered is by the inconsistent and spotty service at Miller Park. Even when my phone says it has four bars, it's often impossible to send a text or post a tweet. Calls are just as bad.

Obviously, just as soon as the new iPhone comes out, I'm breaking my contract and switching to Verizon. But in the meantime, the PR agency that represents U.S. Cellular heard my plight and asked if I'd do a head-to-head test.

Sure, I said, so I jumped up to the Miller Park press box, which has the best view in the house, and during the first three innings of today's Brewers-Dodgers game, I conducted five different unscientific tests between the AT&T iPhone and U.S. Cellular Samsung Mesmerize.

The results were a bit surprising, as AT&T worked as well as I've ever seen it here in Miller Park. And that's not saying much. The U.S. Cellular did well, too, with, a few hiccups.

Here are my unscientific results:
