2 ATT Questions (Upgrade Terms and Tethering)

[abnospam]

Hi Everyone -

Can anyone help me with the following?

1. If my contract is up in August, but I upgrade to iphone 4 in July, when is my new contract end date? Is it July 2012 or August 2012?

2. If I have the pro data plan @ 2 GB and I want to use tethering, but only on occasion, can I add and remove it to my plan when I need it and will it prorate? e.g. like internal data plans

Thanks for the help everyone

1) July 2012
2) I imagine you could add and remove it at will, but I'd call AT&T and ask them for a better answer

I found something in their forums that says tethering can be added and removed at will and the charge and data cap is prorated. Only problem is that this wasn't specific to the iPhone so I don't know if it holds up.
