So I bought myself an iPod Touch 4th Gen 32GB around Xmas purely for music and NO apps. But I've been recently thinking are there any useful tweaks I could use on my iPod Touch if I jailbroke? I'm currently running iOS 6.1.3 Stock. Themes I guess could be one but what exciting tweaks could I install? Also, are there any tweaks I could install to improve performance as it is kind of sluggish at parts, especially my brother's jailbroken 6.1.2 iPod Touch. Thanks.
