Mobile Phones can only Sync with one Library?

Question

Sup all. My current mobile phone is Rokr E1 (the first phone with iTunes), hence I'm exposed to iTunes. The problem lies here. I had this library full of songs. However, recently I changed my com and accidentally lose everything(songs, pictures, videos,etc.). After getting my new com, I downloaded back iTunes and continued adding songs into my phone, but to no avail.
They tell me that a Mobile Phone can only be Sync-ed with one Library at a time, and that all my songs in my phone will be replaced by the songs in my new library (which there is none) if i adhered to it. In other words, I cant add new songs into my Phone without my old Library, but I lost my old Library. Any Ideas how to continue adding songs into my Phone? Thanks. Great Helps Appreciated. =)

Your iPod can only be synced with one computer at a time.  If you try to sync it with a new computer/iTunes library, it will replace the contents of the iPod with whatever is in the new library.  If all the content that is on your iPod is in iTunes, there shouldn't be a problem. Just go ahead and sync your iPod
Otherwise, you are probably wanting to copy everything from your iPod back to your PC first. If that is the case, you should probably disable the autosync functionality first by going to Edit -> Preferences, clicking the Devices tab, and enabilng the prevent iPods,iPhones, and iPads from automatically syncing option.
Before doing anything else,  authorize the new computer with your iTunes Account.  In iTunes, choose Store -> Authorize This Computer and enter in the correct credentials. Either copy a backup file from your old computer to your new one or create a new backup of your iPod in iTunes before letting it sync.
Then right->click on your iPod Touch from under the Devices section in the left hand pane of iTunes and choose Backup. You might also want to take a look at this article to see what it all included in the backup.

Now onto synced content such as music, videos, photos, etc.  For iTunes purchases you can copy them back into iTunes by choosing File -> Transfer Purchases.  For all other nonpurchased iTunes content, see this older post from another forum member Zevoneer covering different software availbable to assist you with this task.

Once the backup has been made and all other synced content such as music, videos, and photos are back in your iTunes library, restore your iPod from that backup you made earlier.  Here is more on backing up and restoring your iPod.
