There are a two ways to do this.
All you have to do is click the button on your safari screen on the bottom left that looks like a book.
Then click history, and click clear.
Go to Settings-Safari-Then scroll down to clear history
touch the app for 3 seconds and it will start shaking
after you take it there is a picture of a trashcan click it
You cannot permanently delete Wi-Fi access from the iPod Touch, but you can turn it off. Go to your settings, and then to Wi-Fi, and then turn it off. If you wish to keep a lock code on it, then go to restrictions and restrict internet access as well as turning off the Wi-Fi.
on safari touch the bookmark icon, go into history and press the clean history buttom
No. Once you delete it you cannot find it. It's like on your computer. You can't find it once it's deleted.
This is taken as deleting your history. To delete your history on Safari on the iPod Touch, tap the book icon on the bottom bar of Safari. Then, tap History at the top of the page, and then at the bottom left corner, tap 'clear history'.
No its private. Just delete your history every once in a while.
To delete them from the iPod itself (this will only remove the icon) hold your finger down on the icon then click the little X. To delete them permanently, open iTunes, then go to Applications on the left hand sidebar. Right click the one you don't want and pick "delete." It will be deleted on the next sync.
If you tap the icon and hold it long enough, the icons will start to shake. When this happens, ones that you can delete will have an 'x' at the top left corner of them. Tap the x and then hit delete to delete the app
no it does not erase purchase history but wipes out all data on the itouch
Downgrading your iPod Touch should not delete anything.
unfortunatly there is no way to delete songs from the iPod touch itself to delete songs you need to do it through iTunes.
