I am thinking about getting an S2 when Sam's puts it on sale for 96cents on Black Friday, but I have a question. My phone ( a Captivate) is about to be a year old (black friday is it's 1st birthday), I was wondering if I upgraded an existing 2 year line with the two year contract, would I be able to put my Sim Card from my Cappy in the S2 and have it work, and be able to stop the data plan I would have to start to upgrade to the S2?

If you upgrade your existing plan to get the new phone then just swap the sim and your good to go. If you upgrade another line besides the one you are using for the captivate you can do the same thing just swap sim cards but the data I'm confused about what you are asking??

I'm asking if I'll be able to put my 3G sim into the 4g phone, and have the S2 on my line, and be able to cancel the data for the other line.

I just got a Galaxy s ii....and I went from a 3G to a 4G. They had to replace the sim card. cause I was going from 3 to 4G

Your are using a upgrade for a difrent line then the captivate is on and then whant to use the s2 on the 1st line and remove the data plan from the 2nd line
If this is what you want to do you can. You will call att and use a difrent phone on line 2 yu will give them the non smart phone emi # and they will remove the data.

Interesting, I just purchased an off contract S2 and switched from a BlackBerry torch without changing Sims. I wonder if this really makes a difference, I am reading H+.

The S2 is not 4G just the skyrocket S2 is. You don't have to switch to a 4G sim for that.
