This is really frustrating as my VPN over 3G does work, but only VERY intermittently. It works 100% over WIFI. So I know it's not the server, I know that T Mobile does allow VPN but cannot figure out why it only works once or twice out of 50/60 attempts?
I have a iPad 2 with latest OS 5.1
Apple kit certainly not what it's cracked up to be.
