mmm you dont lose anything when making an update
You cant update it without loosing stuff sorry :/
No, because the update depends on the base software to be there.
Yea. Go to apple.com and it says there.
Go to software update after plugging in itouch and tapping it's name. Then do software update. Most updates don't delete anything.
It's already out! yaaaa! Go to your nearest Barnes and Noble and ask for the newest software update.
I honestly don't know... Google It.
By asking the administrator.
If it doesn't already come with it then go to iTunes and when your iPod comes up click "Check for Update" Then the proper update will download and install. If you already have iOS 5 and you want iOS 5.0.1 Then you can update directly from your iPod by going to Settings>General>Software Update to auto check for update.
Well, all games need to have the latest software update. But don't worry, all the psp games have the software update already on it so you can update it from a game. And new software updates come with new features like internet radio or inchanced web browsing. You don't have to always upgrade, only when you need to.
Macs come with Java ready to go. You can download updates (See links below) but these will be the same as those available through Software Update.
Update the software if you haven't already updated it (the latest version of software 2 or software 3). This is usually the culprit of most app crash problems.
On a Mac click on the Apple menu icon (top left corner) and select Software Update... from the menu. This will check what new versions of software are available for your computer. Software Update will then offer you the choice to install the available new versions of your software.
