Everything was working fine, i used POOF to hide the icon, and i started having some WIFI issues, thought i will change BL and see what happens, made BootNeuter visible from POOF and i get error launching the app "This application must be run under UID 0. Please check your installation."

How to resolve this?? Help

The Bootloader wouldn't make a difference.

What wi-fi issues are u having?

I suggest a restore in iTunes.

i am able to connect to home wifi which is on DHCP without any problem, but the one at work is on static ip when i enter the details, the wifi shows everything is ok, but the symbol on the status bar on top dissapears.

when i remove the numbers from subnet mask, the wifi symbol comes back, but access to the internet does not work

that is why i thought i should change the BL version from 4.x to 3.x to see if that would have made any difference

what authentication method does ur connection at work use?

Normally "Reset All Settings" from the Settings>general menu fixes that as I said in the FAQ!

To fix booteuter, just install the one from iclarified sources over it. I just had to cause I wanted to uninstall it and all is well again
