1) How to get Google Wallet working on Sprint Galaxy Note II, I haven't been able to get mine to work yet with MC2 and I've done quite a bit of reading on the subject. I'm sure there are numerous users out there in my shoes. Edit: I understand that you already have a link for getting Wallet to work on the older roms/firmware but this never worked for some of us, Wallet quit working for others on MA7 or MC2.
2) Options for managing/swapping internal/external storage, there are many available but most of the specific threads do not specify whether they work with Sprint variant or not. Seems users are at trial/error with this, should be a solid explanation somewhere on recommended methods to use with stock rooted/unrooted rom.
