How To Get Internet With Sidekick Lx On At&t Can I Use Unlimited AT&T Data Plan On IPhone 3G NOT IPhone Data Plan?

Can I use unlimited AT&T data plan on iPhone 3G NOT iPhone data plan? - how to get internet with sidekick lx on at&t

So, now I have a Sidekick LX and I'm really tired. It is too big for me. I have the U.S. $ 1 per day, unlimited try everything, but pre-paid and I like it. I went on a family plan with AT & T for the last year and still have an open line to pay my parents, but I use. I want to buy a second hand unlocked and jailbroken iPhone 3G plan and the SIM card into the phone with AT & T regarding the iPhone and add Unlimited Media / text. Does it work? Basically, I share minutes with my family and with the media and the Internet on the iPhone. I have many threads to read that the numbers for AT & T does not use iPhone data plan and makes you change. When Lustd-out would be able to share with your family continue to minutes and simply add the iPhone data for $ 30, and the texts of 1500 $ 15, or what? Not really unlimited SMS, because I realized that in reality no more text. I just need a good number of texts. In any case, it was almost like the Sidekick for $ 1 per day is the plan. Please someone help me!
