Help Want Docs To Go for $5.55 but do not have phone yet?

[Smudgie]

I have ordered an Incredible for myself and an Eris for my wife. I currently have a Palm Treo 755p and about 2 years ago I paid for the full version of DTG. I use it all the time and will need it on my Incredible. Both phones are scheduled to be delivered tomorrow. Is it possible to use my DTG from my Palm on my Treo or do I have to purchase it again? Also, I would like to get a copy on the Eris. Is there anyway to purchase it now for $5.55 seeing that I don't have the phone yet? I have read where the sale ends today. Thanks
