Even with the 4g plans they still only give you 2gb?
I just checked, and they have a 4GB plan that allows tethering for $45/month. That may be iPhone specific, I'm not sure. I'll ask the salesguy when I go back in about that.
never even reach 500mb a month on my phone. Then again, I don't have that many internet things that I want to look up regularly.
At home, I do use netflix and generally pay no attention to usage under the assumption I'm connected to my home network. It's possible, I suppose, that I'm using 3G without realizing it.
