What does it mean when an app states it has "added support of SD card"?
it means if you have A2SD you can install the app on the SD card
So how would I get that? Is it on 2.1 or 2.2?
What class would you need to have for your phone? I see everything from class 1 to 10...I'm assuming the higher the class the faster, but what would be the lowest class possible to use and be fast enough?
Even if you use class 2 you will be fine as long as you do not need to transfer large files from and to the phone. If you do that often enough, buy something like class 6, that should be enough. If you do not copy large files from and to the phone, class 2 will be fine.
I'm just going to use it for music and apps to SD, so the class 2 should be fine then?
You'll be fine with a class 2 since aside from initial copies, you'll probably be doing more reading than writing to the SD card. Keep in mind that the SD card's class is the minimum write speed in MB/s. But, that's just minimum. When I robocopy'ed my 16 GB class 6 to my 32 GB class 2, I got over 4 MB/s average speed despite the card being a class 2. The class has nothing to do with read speeds, which are normally very high with all types of flash memory.
