If using Windows XP, vista or windows 7 click on the apps tab and when all of your apps appear click one and press CTRL+A, all of the apps should be clicked then. After that just simply click delete on your keyboard and they should all should be gone.
All iPod apps are from iTunes.
It means it's backing up all of your songs , apps and photos while syncing.. That why if you delete anything you'll have all of your data on iTunes
No it does not. All apps from installous are free but you will not be able to sync the apps into itunes. you will not be able to sync unless you delete the apps. If you get appsync from cydia you can sync apps without deleting.
you can search any apps on iTunes or see apps on the home page on iTunes
General way is selecting menu File -> Display Duplicates to list out all duplicated tracks, and remove them from iTunes, BUT this will not delete the file actually. To delete the files as well as removing them from iTunes library, you need to do it manually or use other apps like iTunes Duplicates Cleaner.
(If you mean deleting stuff)To delete songs or videos. You need to do this on iTunes. Remove the designated songs or videos from your iTunes library by right clicking on the song or video and hitting delete. The next time you sync to your iPod from iTunes, it will take off the songs or videos not in your iTunes library. To delete apps. On your iPod, if you hold down the app you want to delete for a few seconds, all the apps will start shaking and x's will show at the top corner of the apps you added (the ones that didn't originally come with the iPod) and if you hit the x, it will ask you if you are sure you want to delete it from your iPod. Accept, and it is no longer on your iPod. You can also do this from iTunes, like the songs and videos. (Unfortunately, there is no way to delete the apps that came with your iPod.) To delete photos. Go to the photo you want to delete and hit the little trash can on the menu on the bottom of the screen. Hope this helped!
Downloading and installing the iTunes software will not delete anything.
Depends on what your interests are. There are all kinds of apps out there.
All you have to do is place your finger on the icon for Skype, hold it for a few seconds and you will see all the apps will start to 'wabble' (shake on the screen). You will then see an x at the top corner of the Skype app, just tap the x and it will delete the Skype app from your device. This method is used for any other app you want to delete. Also you will need to insure that you delete the app from the installed apps list on iTunes as iTunes will reinstall it if you do not remove it from the installed apps list.
your music and apps are all going to be in itunes however your high scores in your apps and maybe emails/notes and settings like your email accounts will be lost (you just have to add them again)
Now you will not delete all your apps. If you restore your ipod it will delete all your apps but you can always re-download for free, even if it cost $ before. (Don't update if you have a jailbroken ipod)
