Since TechEd Europe is just around the corner, and seeing Christian's post and Christophe's post, I figured I'd join the TechEd Bloggers.
Looking forward to meeting everyone at the meet up there!
BTW, If you're on AT&T Wireless's mLife and have a 900/1900 GSM phone, you can activate International Roaming on your cell phone. :) Can't wait to try this out. (Probably other GSM services in the US have this International Roaming available, but I can't verify the validity of this.)
