How do I install a ringtone purchased from Verizon? It does not show up on the list of ringtones. I can only play it by selecting it separately in the txt message area. It is downloaded to my phone, but that does not install it in the ringtone list. The last time I purchased and downloaded a ringtone I spent 25 minutes on the phone with Verizon tech help while they researched how to install it. There must be a better way!
