I get this message here on my iPhone 3G and cannot play any video clip. This is what was done before I get the problem: restored with alt key (iTunes 9) +jailbreak(blackra1n)+ unlocked(blacksn0w). The firmware version is 3.1.2. YouTube used to work perfectly before the restore. Nothing should have changed since I loaded my backup iphone config from my computer. That fails with Wifi and 3G networks I sync with iTunes 9.1 : same I give the device a fix ip address : same I browse from Safari : fails is there anybody who knows a solution that would work for sure?
