VERY NEW want to be sure I'm ok.

[pyrowaves]

MAJOR noob here but I think I understand it all. but want to verify if someone is nice enough to help.

-I have done the unlocking(in the rainbow screen it shows SPL-2.40.Olipro
-My radio is 3.42.50
-I have the kitchen program and am going to build OS how I want(never done it before is there anythign I should know?)
- I have verizon, but I have my old HTC 5800, instead of calling after my flash(because I don't have a second phone) can I transfer service to my 5800 and then back to my 6800 and have everything work?

my biggest concern is flashing it and not being able to use it because I can't call verizon.

Thanks. and btw the site is GREAT.
