So who wants in? The way we all could work together now that we know that it is possible is reporting bugs and known sd roms that actually work with it, how good or well one runs over the other and everything... As well as with Class type 4/10 (Whatever other Classes there are) so on and et cetera.
The possibilities are literally endless now, because with what lil experience I did have with WP7 and WP7.5 I believe it (Microsoft) creates an exFAT partition of your normal card when setting it all up, and so since we all know about creating a dual boot with WP7 (However I never successfully accomplished it, I guess I was destined for other discoveries ^_^ and to be honest I didn't really care too much for WP7 before or after I tried it. LoL!) SD Android so to speak as well as a portion of it (Your SD Card) formated for it in of course Fat32 Primary. So if anybody wants to give that a whack as well might also bang out successful booting of SD/MAGLDR Android too while you're at it. Feel free to report back your findings.
I say if you have a 64Gb microSDXC Card laying around, then give it a shot! Or if you can afford to spend that much as well. LoL
Hope to hear from everyone soon!
