How to fix an iPhone in reboot loop

Recently I have been playing with the internal libs of my iPhone, I tryed switching the CoreText with the old iOS 5.1 so I could maybe fix the unicode of death bug.. Hah!

Turned out my iPhone when rebooted started to reboot endlessly, OMG, my real fear was of being forced to do a full restore and lose my jailbreak

Not until i found iPhone Explorer here: http://www.macroplant.com/iexplorer/

This nifty little program will allow you to make changes in the filesystem WHILE PHONE IS REBOOTING

it helped me changing the lib in the filesystem back to the iOS 6, phew..
