Before I jailbreaked my iPod Touch 4g and downloaded this mod at Installous. It's the one that when you slide your finger down from the top most of the screen, you will see that you can on/off your WiFi/Bluetooth and adjust the brightness. You can also change the WiFi logo instead of the usual signal bar, it changes to a number e.g. -50. When I updated my iPod Touch to 4.3 I think, the jailbreak was gone but the WiFi logo was still the number. Anyone knows how to fix this problem? Thanks!
