I've been googling like crazy over the past few days, looking for any real evidence that people are experiencing problems with iOS 4 on their 3rd gen iPod touches. Every search I do ends up bringing me to lots of people talking either about the iPhone 3G problems, touch 2nd gen problems, or a discussion on jailbreaking of some sort. I've been hesitating to upgrade my 32GB 3rd gen touch to 4.0.2. It currently has 3.1.3 on it and runs fine. Is there any real reason I should be wary of iOS 4 on this unit, or has it generally been fine with nothing but improvements?
