Email with the front camera pic for me works still good, just tested with smscon-editor. (smscon v0.7-2)

It even worked, when I currently have Dummy-APN in use and N900 is using Internet over Bluetooth-PAN and PC-ADSL.
It correctly switched quckly to GPRS, so it can connect to my 3G-operator's SMTP-server, and then switched back to Bluetooth-Dummy. I couldn't connect that same SMTP-server through the Dummy-APN.
