Happy iPhone user here in North Eastern US, but I think your logic (and the TFA's) is faulty: It is completely possible that it is a problem with the iPhone, but one that is only visibly affecting the network when there's a high density of iPhones being used in a small geographical area. It's like the whole controversial 'pre-fetch' setting on Fasterfox and other 'web accelerators'. It's fine for individual users, but it violates the contract of how network clients (browsers) are expected to act. Once there's a sizable number of people using the technology it becomes a problem that affects everyone. To say that the issues only occur in large metropolitan areas does not completely exclude the iPhone itself from being a contributing factor.
