I want to hand down my phone or basically swap phones with a family member. We have a iPhone and non-smartphone both under contract on the same bill. Can we just swap sims and go on about business and our numbers would switch that way or can we not do this? Would it effect our upgrade dates, we are still fulfilling the contracts so I'd hope not?

I'm hoping to eventually ditch the basic phone for the iPhone 6 once the that's out and my contracts up on one of the lines but don't want to mess with anything if I switch numbers.

You will most likely need new SIM cards but it will not affect upgrade dates. The only time a upgrade date is affected is when you buy a new phone.
I didn't think of the SIM cards being different you're right will probably have to go in. So basically the contracts/upgrade dates are tied to the phones? I'm going to have our lines swapped then hopefully it's a simple process. I just don't want to eat up the non-smartphone upgrade in May as from then on I'll be patiently waiting for the 6. :)

Yes you can switch. You will likely need to go to an AT&T store to get new SIM cards since their sizes will probably be different.

You also will need to switch the data plan from the iPhone number to the non-smartphone number. If you don't; the system will automatically add it to the line anyway and you'll get charged for both.

It wouldn't effect my grandfathered unlimited data plan? I want that to remain and def don't want data on the basic phone I'll be using as it can't do much

No, it won't affect your grandfathered unlimited data plan. Go in to a corporate store, tell them what you want to do and emphasize the need to retain your grandfathered plan. And of course be sure to read and understand everything they hand you or have you sign.

well it turns out you can't do this, if you are switching lines and were on a grandfathered plan you'll lose it no way around it. i raised hell over the phone then went instore and did the same no dice.

I think I misunderstood what you were doing. I thought you were switching phones on a line and asking if the unlimited data on a line would transfer to the new phone on the same line. I see now that you were hoping unlimited data would follow the phone to the other line, which it wouldn't. Sorry for any confusion.
