Development for the Barnes & Nobles Nook Tablet has been on the rise, and with more development activity comes more fun things for people to flash. XDA Forum Member CSX321 has released a method to get Google Calender synchronization and side-loading working on the device.

So for now, the only way to get side-loading working is by editing the settings.db.
