Cell Phone Tower

Rob wants to know who best provider is for the iPhone in Los Angeles? Leo says that in a huge metropolitan area like LA, he'll have his pick of the litter. He shouldn't trust the carrier coverage maps, as they are too optimistic. There are third party sites like OpenSignal.com that will give an independent assessment. T-Mobile and Sprint are also good, but they have dead pockets in the suburbs. AT&T and Verizon are best in LA.
