Hi guys, i own an iPod Touch 4G but its running slow (even apps and games) on iOS 6.1.6 but was running smooth on the 4.x Firmware, is there any way to downgrade my Device to an Older, Smoother iOS??

Probably not. Apple is in full control of this stuff. Getting them to allow a retrograde installation is very unlikely... :-( That said, there are a lot of security upgrades in the new versions of firmware.

Apple do not allow donwgrading any of its device.

I guess you should switch...

Ok, Thanks for your replies, Gonna switch to a newer device
