if your ipod touch has lost it touch, that probably means the screen is broken. if it has cracks, there is another sign. my friends lost her touch and had to order a new screen from apple, or go to the store were you bought it.
Yes, the jailbreak will be lost. When you upgrade your iPod Touch software, it is completely reinstalling the software used to run it. When you jailbreak an iPod Touch, you are only jailbreaking the software, not the actual iPod.
look for it
well you better find it!
go to mobleme.com
my ipod touch broke or i lost it i dont know which one but how do i get music onto a new one
There are a few apps out there that find other iPods, but you would need to have a second iPod Touch that has a WORKING finder app.
it gets better
... nothing
When you sync a iPod touch it backs up your iPod and it can download all the songs on your computer (if you choose that option when you go to you iPod setting in music on your computer) :)
no, you can not locate it
It will clear everything your ipod knows about its networks
