I just recently upgraded from an LG Cosmos (not the touch screen version) to the Thunderbolt. On the Cosmos, I was able to go on different sites and download ringtones, and i was able to set them as either a ringtone or a text message notification. But when i download on the Thunderbolt, I seem to be able to set them only as a ringtone, not as a text message notification. Is there a way to download sounds and use them and text notifications?
