I've identified the issue and it is pretty much unfixable without breaking the concept behind SWITCH. It is ROM based and means that for certain types of Exchange accounts, you're out of luck unless you want to manually re-sync each time you SWITCH.
Kind of destroys the concept for me.
@Lenny - try not to comment about things you don't understand and haven't even investigated, and assume that a bug report is a user's mistake. You just make yourself look silly.
Many thanks for SWITCH. I've been giving it a good run around and am very impressed. Besides what you have in your OP, have just found one small (but quite annoying issue). Following every SWITCH, my email and calendar account settings are still in place but they are always marked as not synced in settings. I have to manually recheck the boxes to allow them to sync automatically again. This happens both ways between SWITCHES and in both Sense and GE ROMS. It also happens every time and is easily reproducible.
Just downloaded 17 and all is well apart from no Blinkfeed icon in launcher on a ONE. Or maybe I've misunderstood the purpose of that particular mod.
EDIT: All's (nearly) good now. I deactivated (rebooted) and reactivated (rebooted) and it's now displaying like a champ!.. but it doesn't actually do anything when clicked on, from the app drawer or a screen folder.
Filesonic isn't playing nice with me. I've downloaded the files from points 1 - 4 in the checklist without problems but I am not able to download the Patched Revolutionary Recovery Image and Updated Hboot from steps 5 and 6 respectively. I keep getting the message 'Download Error - Free users may only download 1 file at a time.' I've tried editing my Hosts file/clearing my cache etc.
Any kind soul able to help me out with an alternative link please?
