iPod Help URGENT
my iPod was originally iOS 4.3.3 and it had the full 8gb of capacity, ever since upgrading to iOS 5, the capacity has gone down to 6.4 and I've been searching for answers which are saying that the missing 2gb is from firmware, and I want to know if it is possible to get rid of the iOS 5 firmware, so that it'll go back to iOS 4.3.3 because thats what I payed for.
I am NOT looking to jailbreak, download any third party software or anything like that. I want an answer that'll lead me to do it myself, unless the only option is to exchange it for a normal iPod which does have 8gb.
iPod touch, iOS 4.3.3
