Time Warner Cable
The way I read it is Road Runner Mobile has no caps at all, 3G, 4G or combined on the National Elite Plan for $50 or $60, depending on what other services you have. Only downside is they charge for roaming
They also offer a 4G only plan for $40 and a 250MB capped 3G/4G plan for $20
Comcasts XFinity 2 Go has a 5GB cap for 3G on their 3G/4G plan, but appears to be Unlimited for 4G. Comcast allows for 100MB of roaming data though, whereas TW doesnt.
First Osama Bin Laden and now Steve Jobs, 2011 is turning out to be a great year afterall.
