Answer to "Wondering Quality Of iPod 4th gen"I have the iPod 4. The camera is not good but not bad. There are very very few apps/games you can download. You can still download any song. Youtube is not updated. Bing doesnt support the ipod 4 anymore (because it is so old) . i recommend you get at least the iPod 5 because you cant do much with the ipod 4 and its not worth the money. Getting the ipod 5 may cost more but is a LOT better in the long run.
Answer to "iPod disabled and no way to fix it!"Unfortunately, you have to use a computer to undisable it. I have the iPod touch 4 also and once it was disabled so i had to reset it using a laptop. When you reset it you lose everything unless you have recently connected your iPod to the laptop or computer. I would try going to the geek squad at best buy.
