So you got your shiny new iPhone, synced it up to your home PC and got it all working sweet. Now you get to work and want to listen to some tunes, but you have wasted your iPhone battery on the train playing Super Monkey Ball. You plug your iPhone into your work computer to find iTunes it decides to delete all your songs and applications because it is not the original sync computer. :@
Luckily there is a solution! By default your iPhone and iTunes are set to sync your music library automatically when connected. Obviously this occurring on a computer other than your original sync computer will cause your iPhone to attempt to delete all the files and resync. But you can tell iTunes not to auto sync by doing the following before connecting your iPhone.
Select Preferences from the Edit menu and select the last tab Syncing. There is a checkbox here called Disable automatic syncing for all iPhones and iPods, which if you select it will stop iTunes from syncing automatically. Click OK and connect your iPhone to you PC.
Once it connects, select Manually manage music and videos, from the iPhone home screen and click apply. You will then be able to access the Music and Videos from your iPhone.
These steps will also work for your iPod.
Unfortunately this will only work if both machines are either Windows or Mac.
