[Q] Difference between P6800/P6810 and SCH-i815?

view story

http://forum.xda-developers.com – Hi, I'm looking to get a Galaxy Tab 7.7 and it seems the cheapest used one on ebay is the SCH-i815. I assume the difference in model number has to do with the ability to use 4G LTE on Verizon, which I'm not concerned with really, except that this version seems to be selling for cheaper. My concern is when I root this tablet can I use the any of the ROMs listed under the development section? All of them seem to be listed for P6800/P6810 and when I search within I don't find the term i815 or 815 as a separate thread or a within any of these threads. Thanks (HowTos)
