Had some problem with YouTube on sis’s iPhone 3G after jailbreaking the 3.1.2 firmware sometime had. The application keeps prompting “Cannot connect to YouTube” whenever she tries to launch YouTube. After Googling, realized that the problem is due to blackra1n.
Most websites ask you to install PushFix from the cydia source – iphoneil.net. But the application cannot be found! Found another source to restore the YouTube certificates – cydia.pushfix.info. Sis is enjoying herself on the iPhone once again. Yay!
