Just purchased one myself today. Theyre still $20, get them while they're hot!! I still think Verizon should have gifted these to Thunderbolt owners, but I digress... Hopefully I do this right. I'm charging it until green while powered off, then I plan on booting into recovery and wiping the battery stats, running my phone until it's out of battery, then charging it until it's green again. I think that is the proper procedure, if there is one, to calibrating the new battery. One thing to note: the Rezound battery is noticeably heavier, not by much, but if this may bother some people.
I also got a chance to check out the new Razr. That phone is sick, I'm so jealous!! Beautiful screen and runs smooth as any phone/rom I've ever used. Nexus-schmexus, get one of those if your contract is up! It is huge though. Thin it may be, I don't know if I'd be able to tolerate a phone so wide and tall. As for the Rezound, meh. Between all of the devs for the TB, I don't think there will be much of anything we will be missing out on for a new HTC phone.
*ps- This should be stickied, and posted in the Thunderbolt battery discussion, if it hasn't been already
