Sprint has allowed Google Wallet for quite some time, a buddy of mine on Sprint uses it on his Galaxy S3 all the time. For Sprint users, the app just needs to be updated for the One (as far as I'm aware anyway). AT&T is another story altogether .. the only devices they allow Wallet on are non-AT&T branded devices like the Nexus phones. It would be nice if that were to change, but I'm not holding my breath.
AT&T, Verizon, and T Mobile are backing a payment system called ISIS. I doubt they will give in on allowing Google Wallet anytime soon, if ever. I hope I'm wrong, honestly, but as I said, I'm not holding my breath, lol.
I am having a difficult time understanding how restriction of Google Wallet doesn't break the laws regarding the use of the LTE spectrum. Unrestricted access to software and services is part of that law.
Gunnyman is right. As part of the block C purchase from the government, there is a clause that states that the carrier is not allowed to restrict access to software and/or services (paraphrasing of course)
