I'll try to make it as short as possible, but include the pertinent info.

I ported over from Centennial Wireless when AT&T bought them out. Had 2 lines, i only upgraded one to get my 9700, kept the old phone i had on the other. My 9700 line has the Blackberry plan and messaging add-on. So, fast forward, the Captivate is about to come out. i want to get it, BUT, will i have to add a second data and messaging add-on to it, increasing my bill by the $30 or so for data and $20 i think for the messaging? because i want to keep my BB and have the Captivate also.

Not sure if this is 100% correct, but I'm 95% sure.

If you only have one line you only need one data plan. You can swap the SIM from phone to phone using the same data plan, but you would need to call AT&T each time you switch the SIM from phone to phone to reactivate it.

no, i want to keep both lines - 9700 on one line, Captivate on the other. have a family plan that ended up just ME, and since im paying, figured id use it, but not if i have to add that much to my bill.

Two lines would require two data plans.

well question.... if i already have unlimited data on my Blackberry, would it be possible at all to get that switched? to drop the data amount on the line with my Blackberry and have my unlimited transferred over to my Captivate once i get it?

As of September 2009 all new phones or subscriptions are subject to the new tariffs. I don't think you can sustain that unlimited account if the device is changed.

Yes you can keep your smartphone unlimited on that line, and change the 9700 to the other and put either a 200mb or a 2gb.

You can change from smartphone to smartphone and still keep the appropriate unlimited data feature. Just have a supervisor switch it for you. Do NOT go to a store for feature support.
