A record of the sites you've visited will be erased, but your bookmarks will still be there.
Depending on what your device is. LOL :P
It depends on what type of restoration you are preforming on your iPod touch. It you are resetting the network then yes all your tabs and bookmarks get erased. If you are resetting settings to factory default then no your bookmarks will not be erased. If you are restoring your whole iPod completely then yes everything on your ipod will be erased.
I think that you are asking if using a file wiping program will delete your browsing history and cache. If that is not your question, please provide more information. A file wiping program, used correctly, will remove your history and cache. You would need to identify the history and cache directories. This will vary on which browser(s) you are using. If you are really paranoid you could wipe out the entire drive. That will erase your history and cache and EVERYTHING ELSE. You would then have to reinstall your operating system and applications. If your data was not backed up, it will be gone forever. If you are just trying to free up some space, do not use a wipe program. All the browsers I am familiar with have settings to clear out history and cache.
In internet explorer, click on TOOLS then Internet options then clear history. You may have found the Clear option to help you clear your history and empty your cache file in your browser's settings, but all these will not protect you. Some files can not be Erased. For a complete and safe erasing, I would recommend Privacy Eraser http://how-convert.com/privacy-eraser-pro-erase-internet-history-protect-internet-privacy.html It cleans up all the tracks of Internet and computer activities. With simply one click, Privacy Eraser Pro allows you to erase internet history, erase browser history, erase address bar history, erase cookies, erase internet cache, autocomplete memory, saved password, index.dat files of your browser, and Window's swap file, temp folders, run history, search history, open/save history, recent documents and more. This will also speed up your computer.
Do you mean HOW TO ERASE or did they erase by themselves and you want to know why?
Yes there are many Apps out there ex: Find My iPhone and also if you have iCloud account setup you can remotely erase the data from lost/stolen iPhones
To 'unjailbreak' an iPod Touch, you have to do a system restore, which is available in the iPod Touch home menu in iTunes. This will erase all content that is on the iPod Touch, including bookmarks in Safari and contacts in the Contacts.
You can set up bookmarks or sections and you could use the document map or the Goto command (F5) to go to the part of the document you want.
If the browser history has been deleted, you cannot check. The browser is the only place that stores the history and cache.
Did you try disconnecting the battery for five minutes? Most OBD II code readers have a reset or erase feature that will erase the codes and reset the computer after diagnostics are complete.
Ok here's how1: Go to Settings2: Click on the "Safari" Tab3: Click "Clear History" and Confirm (You can also Clear Cookies and/or Cache on this Page)
keep clicking it then it would erase.
