You can't get tethering with AT&T without losing your unlimited plan. The unlimited data plan runs $30 and the tethering runs $20. The 2GB plan is $25 and an extra GB is $10/GB. My math doesn't add up to an extra $5 per month. How are you coming up with that?
My data plan is $25/data, $10/Tethering, $10/extra GB...$45/month total, or $15 over what i was paying for the unlimited plan. I thought this was the norm? Kind of glad it was pointed out because i need to double check it and make sure that's the rate im still being charged (it is the rate i was charged for August atleast).
And i thought my post made it pretty clear i knew you couldnt tether with unlimited anymore. The problem i always had with the JB method was the fact that once you update and the JB isnt good anymore, neither is the free tethering...not to mention the stories of people being bumped from unlimited simply based on their high usage of JB'ed tethering.
