A couple of entries have cropped up in my phone calendar and I have no idea where they would have come from.. Can anyone suggest sources of info for the calendar?

Apparently in 3 weeks time i have "Last espn payment to mum..need to setup more"

I know ESPN is a sports channel, but I dont own a tv, nor do I watch sports.
Also in a couple of months, I'm going to "Me & Ravs Wedding" - I don't know anyone called rav, and have no plans to get married any time soon

So, I'm wondering if some plugin could be polluting the calendar but I'm not sure which plugins do..

Can anyone think of any software on the N900 that fills the calendar? I have one work email account set up on the phone with only 5 mails in, no meetings. I used to use the pidgin facebook plugin but switched to jabber because the other had bugs (deleted the plugin) - does facebook have a calendar? How do I look in it?

My N900 never set me up a wedding! I'm going to sulk now!

That does sound decidedly odd, though. I hope someone has a solution - I'd hate poor Rav to be stood up at the church.
