Accessing, thanks for the update, we appreciate the hard work! I can't wait until the project is finished but understand it's gotta be right. Take your time and if there is testing needed I am available.
If anyone wants to play around with a Sense 2.5 build on a Verizon phone, Twisted Dan's Goodsense LT 1 works well. It's a sharp ROM with very few bugs.

It's not a light build on a Verizon phone, like 6.1 would be but I have run it for a month and with a little tweaking will consistently stay around 80%, it's not great but does the trick and gives you a feel for 2.5.
