I dont't know if this is usefull to anyone but you can browse you complete iphone filesystem if you have a jailbroken phone by doing the following:
Your phone needs to be JAILBROKEN to do this:
1) ssh to your phone
2) cd to /var/mobile/Applications
3) There will be a couple of directories with cryptic names... find the directory with the MobileFinder.app in it
4) cd to the Documents folder in that folder. This is the folder where MobileFinder saves its data.
5) enter 'ln -s / IPHONE'

now you have created a hard link to the root directory of your phone. This is potentially dangerous and could mess up you phone if you delete/change important file. If you do so don't blame me... ;-)

Thanks for the info but to clarify for the less knowledgeable like me, exactly where do I enter this?

You need to have ssh program (putty on windows,ssh in the terminal on mac).

On the mac,in the terminal enter: ssh root@<iphone-ip>

Link Set succesfully , but mobilefinder crashes when tapping iphone.
nice try.

Need more clarification on terms ssh and cd.

I have terminal but must have entered wrong text...help!

ssh = Secure SHell which is the way of accessing the iphone remotely thru wifi or tethered to usb

cd = Change Directory which is a command found in unix and msdos that allows the user to change the working directory they are in

Also note that these are "terminal" tools meaning you will see NO GUI when using them

@outofbreath: neat find buddy.... it kinda shows that apples sandbox isnt as secure, but if you need a jailbroken phone to do this theres not much application since ssh already gives you remote root access and theres other phone based browsers that give root acces too

Now if you could modify the the original app to install that symlink on its own it would be useful for "official" iphone user

And by the way, CaPs MaTtErS. If command says "cd", then type "cd", not "CD", "Cd" or "cD".
