So I'm running an 8GB 4th Generation iPod touch running iOS 5.0.1. My warranty is out because of some physical damage taken on it. This physical damage (chipped/dented in the lower right hand side) has been allowing water moisture to seep in and damage my A4. I get lag (E.G. Multitasking bar, Voice Control, Opening/closing folders and apps) on a regular basis, and some apps (particularly the ones that require a lot of power) will sometimes quit. I really only use my iPod touch for music (Music App/Pandora), social media (Facebook, iMessage, Messenger), sometimes as a camera, and for light gaming (Fruit Ninja, Death Worm, etc.). I've been thinking about jail breaking since my warranty is already void and I'm getting an iPhone (or a WP7 is Verizon gets a new LTE one) in April. What would be some good reasons to? I don't necessarily care about themes. Is there anything to help boost my processor? What are some good extensions?
