Stuck in new Bootloader 2.04/2.05 from the bell/VZW 3.3 ROM, Help is here now

OKay... checking all 5 pages... anything for upgrading a Sprint 6700SP BL to 2.xx? Currently at 1.00 I'm a TOTAL N00B, and I wanna convert my(salvage) Sprint to Verizon as a backup to a flaky LG. (You'd be surprised at what you can find in a garbage bin) Natch the V_Store says "Can't be done", but we all know that's B.S. Also, have looked at the Tut.'s, anybody ever do a Tutorial to convert AND upgrade the 6700? Like I said, I'm a n00b and I'd feel better if I had a walk-thru. Thanx temp-999
