Open the message and the ringtone will start to play. Click on options and select "save as ringtone". It is now saved as a ringtone and you shouldn't have to worry about ringtone size. Most of mine are around 350KB. I probably have 30 ringtones on my phone so far. By the way, my phone is the LG env2 and I was also told that on most Verizon phones that the ringtone cannot be on the sd card. It has to be saved on the phone memory.
