I apologize if this is a double post. My first submission seemed to get lost.
I had success up to a point in using the process described.
I am using a memory card attached to my laptop via a USB adapter, as opposed to a direct USB hookup from the phone to the computer. I have created the 3g2 file by following the instructions, and I moved that file to the DCIM>100LGDCF subdirectory on the memory card. When I re-inserted the card into the phone, I went to the Menu>Pictures>Photo Album>Memory Card subdirectory. The 3g2 file is visible, and I can play it using the Options key.
This is where I get into trouble. When I use Options>Assign, I do not get any other menu choices. It automatically assigns the file as a screen saver, with no other choices available.
Does anybody have any idea what I am doing wrong, or how I can get past this point to assign the file as a ringer.
I am actually using the Canadian version of the Rumour (sorry, the Rumor - I was using the Canadian spelling) on the Bell Mobility network. However, I assume that the programming is going to be the same, regardless of the country of origin.
Thanks for your help.
