I signed up for mytripjournal, but it doesn't appear that you can't post from a mobile phone. It appears that you may be able to post from your mobile phone to travelpod.com. Any recommendations?

I'm basically looking for an application to be able to share text and pictures on a future trip. Since I won't have my computer, and it is unlikely that I'll have a lot of ready access to internet cafes, I'm looking for someplace that I can post to from my Palm Pre. I will obviously load better pictures from my camera after I return home, but I'd like something to be able to share with friends and family on a day-to-day basis.

Of course, I can use Facebook.

Any experiences or ideas would be greatly appreciated.
