I picked up the new T610 a few weeks ago. I decided on this phone because it had bluetooth and a camera. I've been pretty disappointed with the bluetooth support in XP, but I am quite happy with the camera. After emailing some pictures around I decided to setup a “moblog”. As always, I decided to build my own application rather than using existing websites.
The version of the moblog updating tool I wrote last night is able to get attachments from POP, and FTP them to another location and generate an RSS feed for the entries. Considering it was written in one night, there is some pretty hackish code in it, but it works. Tonight I'm working on re-architecting to support plug-ins for publishing. I'd like to support some of the blog api's and some of the other services available.
RSS Feed (location will be changing soon)
