I have v3 working great, found some apps that loop it as well. I'm still having problems with apps2sd (v1 or v2). I saw your post and wondered it I could pick your brain.
Do you have any steps to put this in place? I've purchased a class 6 MicroSD for this but I either get a hung unit after reboot, or the app to partition just hangs. I run Linux at home so ext3 should be easy to add to my Micro.
I would appreciate it.
