I could speak broad-based.
It's not that type of idea. Fees, or even making exclusive agreements with certain credit cards being only available on certain phones is not anything that anyone has ever told me they're after. Everybody wants everything available.
I think Caroline said it best, the wireless companies want it set up so if there is a dispute, it goes to the bank, it goes to the credit card company. It doesn't come to them. It's easier to just be out of it.
