Okay, after having the issue of my Calendar not syncing with my laptop (or facebook) and my Today theme not showing my calendar items I have decided that perhaps I should revert my phone back to the factory settings and OS.

This issue only seems to have come up since I upgraded the OS last night.

How do I reset my phone?

You can't reset the OS. What ever OS is installed, will be the OS, even after a wipe.

To wipe the device: Options > Security Options > General Settings > Menu > Wipe Handheld

Damn, so I guess I would have to "roll back" the OS then? Like I said, this syncing issue only happened AFTER I upgraded the OS (see the sticky link) and it's a bit of a pain...

Or you can use JL_Cmder and choose option #5, reset to factory.

Does that reset the OS?

No, the OS will stay the same.
