Hello everyone, My sister has a 2nd generation iPod touch. Currently, it's on 4.2.1 and jailbroken. She has recently been complaining on how it is slow sometimes and how some things randomly just crash. I have SHSH blobs on that device for 3.1.3, 4.0, 4.0.2, 4.1, and 4.2.1. In my opinion, iOS 4 is generally slow on the iPod Touch 2G and iPhone 3G. My sister usually doesn't mind it, but she has been commenting every now and then about its slowness. I want to give her the best experience with her iPod until she gets a new one. What do you guys think I should downgrade it to?
