我記得 iPhone OS 2.0 開始就有了

Some information about the iPad's security features is apparently not well known, so some of the concerns about the device might not be warranted. For example, some industry analysts interviewed today were unaware that the iPad ships with a native IPSec VPN from Cisco Systems Inc. One analyst said there is wide speculation on the Web that a third-party VPN would not be supported, calling into question whether data transmissions would be secure.
However, the Cisco IPSec VPN can be found in the iPad, along with a section to make settings for other L2TP and PPTP VPNs. All three are located under the setting icon and then under "networks" and likely require information from system administrators to be fully configured.
