Hmm.....I think apple will pull this app and enable the kill switch for this one.
On another note, AT&T should think about allowing us to tether without charging an extra $20/mo. I believe that will stop a lot of this "getting around" things. in order to tether you have to switch to the new plans and pay an extra $20 without any additional data added to your account? BS...that $20 should at least come with an additional 2GB a month (for a total of 4GB). Otherwise leave it at 2GB and let us tether for free (of course we will go over the 2GB limit anyways, then charge us).
Just my thoughts on the manner. I will be using this app and it does work btw.
