[CentOS] CentOS VPN server for iPhone

So far, OpenVPN has been working very well for me. Unfortunately, the 
iPhone doesn't have (yet?) an OpenVPN client, so I'm forced to work with 
what's available.

The options are: L2TP, PPTP and IPSec. If you were to install a VPN 
endpoint on CentOS, which protocol would you prefer? The condition is to 
avoid shabby VPN servers that make the system less secure. I've seen 
some PPTP servers for Linux in the past but I was not impressed with 
their security track record. I'm not necessarily talking about crypto, 
I'm talking about the way the application is written.

Another condition is ease of installation. I will compile from source if 
I have no other choice, but I'd rather avoid wasting time with that, as 
I'm quite busy with non-tech things nowadays. If the application is in a 
repo somewhere, that would be perfect.

Thanks!
