I can't say which firmware this problem might have started in, but it seems like at least in 2.2, I can't seem to connect to any of it VPNs when I am on a 3G connection. I distinctly remener this to have worked for me in the past. When I turn ok wifi, and obviously when a wifi connection is available, I can connect using vPN without issue. However, on 3G, it starts to connect but then fails after what Seems to be about 30 seconds. Has anyone experienced this problem, or better yet, no how to fix it? Thanks!
