on my husband's samsung i760, when he gets a new text message with vito sms-chat 1.1, he gets a notification tone. When i use the same prog on my verizon touch, i dont hear anything when the txt message pops up. my husband has tried changing the default tone to a longer one and that still hasnt worked. any other solutions? (yes, my sound is on, and other noob troubleshooting methods addressed)
