I know that itouch only holds certain types of photos like JPEG. I synced some photos and most of them are in JPEG format. However, many of them look broken, like having lines going through them and shifting to one side. What is wrong with my itouch?? Secondly I am currently using 2 converters to convert videos that I want to sync to my itouch. First one to fit into the second one. And the second one converts videos to mp4 format. Is there an easy-to-use converter that can convert most of the videos?? Thank you^^ addition: I have heard about jailbreak. What can you use it for? and is it safe for your itouch? And do I get into trouble for doing that?? like when I send my itouch to get it fixed??
