I know you're focusing on Lewa and Ligux more than Joy, but thought I would still report errors/issues just for development sake.
The only error I've been getting is when my corporate email tries to activate a security protocol. So, at this point I can't get exchange up and running. I'm going to try a cache/delvik wipe and reboot. I'll let you know how it goes.
The other issue I'm running into is the calendar not showing my google calendar appointments. When I click on a date it shows up empty even though the calendar is set to sync in the account settings.
Having fun with this one. Thanks for all the work!
