We blazed through another show today, talking about Verizon's plan to offer the iPhone next month -- great news if you're an iPhone user on a different network, or a Verizon user who really wants the iPhone, but probably bad news for those of us on Verizon who don't want the iPhone, since it's going to mean additional demand on Verizon's data network. Speaking of which, T-Mobile, which operates in the US and in Europe, is telling its British customers that they're going to be limited to 500 Mb of downloads per month -- a dramatic slashing of the limits, and a lot less than a real-life user could easily burn through in a month.

Look for the answer in a Wise Guys video recap coming soon.
