Now that we consumers have tremendous flexibility in choosing a cell phone provider thanks to the number portability rule that took effect on Monday, I was wondering if anyone (pgary perhaps?) has a list of frequent flier mile earning opportunities from the various major cell phone service providers (e.g. Verizon, AT&T, T-Mobile, Cingular, and Sprint). I'm likely to switch my provider soon and don't want to miss out on the possibility for a frequent flier mileage bonanza. Any known promotions?
