iTunes should give you a list of backups to restore onto the new phone.

If it does not, there is no way to perform a partial restore using iTunes.

iTunes backup files are located in the following areas on your PC depending on your OS:

On a Mac: ~/Library/Application Support/MobileSync/Backup/

On Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\

On Windows Vista: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync

Remember:

    If you choose to set up as a new iPhone or iPod, first transfer your purchases and other data, then back up any important backups of that device you want to retain from the backup folders listed above. iTunes only retains one sync-generated backup per device, and the first sync after setting up as new will replace your previous backup. If you change your mind and want to restore to your previous state, you will have to do so from a backup that you have retained through your periodic backup routine. If you have Mac OS 10.5.5 or later and use Time Machine, Time Machine may back up your backup. Copies of a backup marked with a date and time stamp created by selecting to "Restore from the back up of" are retained by iTunes and not overwritten. For an example of a backup with the date and time stamp in the device name, see the picture below in the Deleting a Backup section.

If you want to restore ONLY the DVDP iOS app*, you'll need to perform a full restore on your device, sync your collection with the DVDP Desktop app, perform a full restore of your current setup, sync with the Desktop again.

(*in theory)

If you are unable to restore iTunes iPhone backup then you should use effective third-party iPhone Backup Software and create fresh backup. If you search online you will find numerous software which can create backup of your iPhone data. I had used Cucusoft iPhone Backup Software which is really trustworthy. So, you can try this.
