I had my iPod touches replaced today at the Apple Store due to some battery issues. My iPod was on 8.2. The replacement is on 7.0.2. No my question is, should I update it to 8.2 or stick with 7.0.2 and Jailbreak? I'm not sure what the benefits would be besides the fact that it will obviously be quicker on iOS 7 that on iOS 8. It's used soley for music but I do like the customisation of a jail token device. The fact I can remove icons names etc. What would you do?
