Blogger Mobile. Blogger introduces mobile-phone-to-weblog posting. Send an MMS/email message from your cellphone to the specified email address, and Go.Blogger auto-generates a new random blogspot URL hooked to your contact information. (The URL can be changed or merged with your existing weblogs when you "claim" your number on login.) More from Blogger Buzz (with jingle), Blogger Help, Bizstone, and Youngpup. What do you think of this compared to "moblogging" via Flickr?
Post to a weblog via SMS. Just this weblog, unfortunately, not your own. I tried it with my Voicestream phone and it works. I'm surprised there aren't more wireless blogs out there that use SMS. (Or have I just been missing them?)
