I was with some friends, and they took my ipod touch from me and started messing around with it. And i was like, "ok, can i have it back now" and they gave it back and it had a password on it (mine never had a password). so i asked for the password, and they said that i had to guess it. So i did, and it didn't work. so i tried again and it locked for 1 minute. No big deal, right? so then i try again and it locks for 5 minutes. now i start to get worried. then they take it, and mess with it, and it screen locks, or shuts off, and now it wont turn on. My friend told me to plug it into my computer and try to reset it or something, but my computer doesn't register that it's plugged in. what do i do??!?!?!??!?! my ipod is my life!!! help!! (and if it's possible, i really don't want to lose my photos).
