I installed TomTom on my iPhone, but it had the icon of “Shazam”. Searching the interwebs I found various fixes all talking about removing the application and rebooting, but there is an easyer way, here it is:
Navigate to the following directory on your iPhone (using WinSCP, iPhoneBrowser, Putty or MobileTerminal)
Rename it to com.apple.springboard-imagecache-icons.plist.fuckedup or something similar, just in case the sky falls on your head.
Now respring et voila!
