I bought an unlocked 7100g. I am a tmobile customer so I am going to download the new software update for the 7100t. The ringtones for the 7100g are a lot better. How do I keep the ringtones that I had and then transfer them to the new software after I run the update. Is it possible to restore using the desktop manager just with a selective backup or is there another option. Thanks in advance for any insight.
