I have been dealing with AT&T the past two months about the supposed 5% crap. Last month my brother got throttled when he hit 5G, which I think is fair. However, the next month he got a notice after 100mb saying he was in the 5%. The next day he was throttled, this all took place within the first week of the billing cycle. Placed a call to AT&T and nobody could give me a good reason why. One of the reps told me that she has repeatedly gone over 10G a month trying to get the 5% message and has not received anything. She passed me onto "their" data department and he was useless. He tried to give me an example of how it worked for the 5%. "If I lived in an area where nobody uses data on AT&T and I happend to use 500mb then I would be throttled". This is total crap. My brother tried to use google maps for directions as he was lost and he said it took almost 10 minutes for it to load up and give hime directions. I am truly considering canceling all of my lines, and I have been with them since Cingular. Like everyone else already stated, at that time they pushed the unlimited data plan and I was allowed to use it for tethering before they started to realize people using the phone as modems. Even their customer service rep back at that time said I could as there was not a clause when I signed up back then.
