I'm doing everything correct on the computer, but when i try to add the server info on my iphone, i also do everything correct by putting the IP address followed by the 5900 port, and the password, then clicking save...but after i click save, it doesn't show the desired name leaving me with no choice of connecting. i've tried this many times and still doesn't budge. any help?

Same here, also saw another report on this issue on the VNsea bug report (google code)

I have exactly the same problem - no matter what server details I put in- clicking save just takes me back to a blank VNC servers page. Very strange and annoying - anyone find a fix?

You have Unlocke/jailbroken/activated with iLiberty+ I assume.
There was a version a few weeks back that had a bug in it that caused this. In newer versions this is now fixed.
Either you do it all again with the latest version, or this(copied from iLiberty+'s own bug fixing blog):

Manual Fix: If you don’t wanna install Installer again (with the new patched script), you may enter the following command in shell (through SSH or Term-vt100) to fix the issue manually:

chown -R mobile:mobile /var/mobile/Library/Preferences

Thanks for the advice - I have another question for you though - I have BSD sub installed and open SSH but don't seem to get an icon for it after installing - is that gone wrong somehow? I get a message saying loggin in will take 30 secs withkeys being generated after I install SSH and that's it back to the springboard and no icon.

Thanks theplague, it works exactly the way it should.

bindy, I don't know exactly why it happened, but I just installed BossPrefs (or any other services-like apps) to switch SSH on and off
