Can I use a grand fathered AT&T unlimited 3G SIM card in a 4G AT&T iPad? Will it get 4G speeds or is AT&T using a different type of SIM card for 4G?

Do you think they would grand father my 3G unlimited account to 4G unlimited?

I will be taking my iPad 1 and iPad 3 directly to the closest AT&T store to let them setup my new sim card from my old.
 
Yes, AT&T is allowing unlimited ipad plans to be grandfathered to the new 4G iPad. Just switch sim cards. If you have trouble, call AT&T.
 
Would it be advisable to, say, purchase one of these unlimited SIM from eBay for ~$400, pay the $30 every month and tether your iPad to all of your devices?
 
I am in your situation. Read on another site the following:

Go to att.com/ipadlanding, login to your account and adjust your account to reflect the iPad LTE’s IMEI and SIM card number.
I did this from iPad 1 to 2 and it worked flawlessly.
I will be doing it 3/16 so fingers crossed.

One of the main things mentioned in another section is to completely power down all the iPads in question so the transfer can occur cleanly.

I already checked this site out, and there is a spot to update your device info.

Here is what I am planning on doing next Friday:

1- Power down completely iPad 1.
2- From the unopened box of new iPad grab the information (IMEI and SIM card number) and update that in the unlimited data account information at the ATT site.
3- Power on new iPad. Confirm settings are correct for unlimited data, etc.
4- Power on iPad 1.
5- Set up new email address/password following the procedure on the actual iPad for adding a data plan (I remember this being fairly easy the first time).
I am pretty sure that I cannot get unlimited with both iPads, but would be nice!

Someone mentioned that the SIM card may be completely different so switching it out may not work correctly.

You can thank people like this for losing the iPhone Unlimited Data Plan!
