There's the iPhone 2G unlimited Edge loophole trick. I'm not sure if they patched the bring the unlimited Edge over to 3G part, but the actual iPhone 2G can still be used to get a $20 unlimited 2G plus two hundred text messages data plan.

See response 2,3 and 4
 
That's not an AT&T plan though ... and I read somewhere else that StraightTalk will cancel your account at 6GB of data.
 
Obviously this won't work with EVERYBODY (but if you get a n00b supervisor/manager and you are OUT-Of-CONTRACT)....try threatening leaving your current cell provider to their direct competitor and take your entire "Family Plan" with you.

Then when asked what it will take to keep your business, throw in the "I want the unlimited data plan on my line" bone and see the response.

This worked for me several months ago when I threatened to take 5 VZW lines to AT&T and got lucky when I got a a "friendly" manager who decided to make a "one-time" exception for me.

Worth a shot.....but remember to remain calm and be respectful. Good manners goes a long way.
 
Keep in mind, even if you get unlimited data back, you'll be throttled at 3GB (5GB with LTE for future phones) anyway, so might just be better to stick with the unthrottled tier.
 
Straight Talk iPhone 4 user here - still in my first month of service. Haven't experienced the cut-off myself, but from what I've been reading it seems the 'undefined' data limit is somewhere around 2 gigs. If the above mentioned 6gb limit is true, that makes it that much more awesome.

They advertise as 'unlimited' data, but obviously it's really not. Still, at $45/month unlimited talk and text, with 2gb of data is a steal. I'd say for the average user (read: not tethering 24/7 and/or streaming hd video all day) it's a fantastic plan. I'm an 'average' user (if that exists) - check email, talk, text, some gps/maps, light gaming, a few vids, and I've only used about 200MB in the past week. For me, it's perfect.
 
any loopholes to get att unlimited data?

Three that I'm aware of but there may be more.

Recently a friend got AT&T to enroll him in the same unlimited plan, I've had for years.

The following day a supervisor called to apologize for their mistake. Being an understanding guy he said he understood & chose a tiered plan.

Much to his surprise, the supervisor thanked him for his business and issued a $100.00 credit to his account. Just proves nice guys don't always get taken advantage of.

They keep the algorithm for determining "excessive" data usage quite secret. Tethering is not permitted. The limit appears to be based on a) daily data usage, with several consecutive heavy usage days generating a warning b) historical monthly data usage, with an occasional extra heavy month being okay, but not a lot of 6GB+ months, c) actual monthly usage.

Some people have reported using 6GB in a month without a warning, some have gotten warnings after using 2GB in the first two weeks of the month.

I think they keep it ambiguous for a good reason. If it were a hard limit there would be a tendency to not do things like using Wi-Fi when available for data intensive tasks like transferring videos or high-resolution photos, until you were close to your monthly limit.

The other option is Red Pocket (AT&T as well), where 2GB of data, plus unlimited voice and texts are $59.99 per month (a bit less if you purchase the refills during a 5% off sale at callingmart.com).
