menu button --- Profiles --- advanced --- choose the profile you want to change and click on it -- scroll down to SMS text and click on that...You can choose the Out of Holster and In Holster tone....just click on the "ring tone" for each and find the one on your phone you want to use.
Does the 8900 Curve not have the same custom ringtone features as the 8310 Curve out of the box? I like having different ringtones for different contacts. I am hoping they would move forward and allow us to set txt tones as well, not go the other way and take away individual ringtone.
