VPN is now there - It wasn't prior to the update. Before 1.1.3 if I went to Settings > General > Network the only option I had was Wi-Fi, now theres a VPN selection.
I can't test it now because I don't have a WiFi connection but it seems pretty decent..
The options are L2TP & PPTP
Server:
Account:
RSA SecurID (On/Off)
Password
Secret (L2TP Only)
Encryption Level (PPTP Only)
Send All Traffic
Proxy (Off/Manual/Auto)
Since I"m not Jailbroken anymore I can't take a screen shot for ya!
