Yes, I have. It appears that this phone is too new and the 3rd party suppliers for cell phone software do not offer it yet. However, I called Sanyo and they referred me to www.futuredial.com. They have limited software (phone book) available now for $50. Hope this helps. Please let me know how you fare with this I am a bit reluctant to shell out $50.
yep it was too new untill now. bitpim http://www.bitpim.org a free multiplatform program Window OSX and linux seems to work great. I used the sanyo cable I originally purchased with my scp-4900. convieniently it works on the RL4920 and the PM-8200.
I was able to upload the phone book, a calendar, midi files and wallpapers as well. though the only way I have been able to get qcp files is using the web.
