The easiest method to add your Hotsync name to Garnet VM(without actually Hotsyncing) is installing an free app called changenamePRC, worked great for me. Just make sure your Hotsync name is properly aligned taking into account any spaces. I was able to register most of my paid for apps I had left over from my Treo 700p.
