I'm a sidekick three user but I'm thinking of switching over to the Droid on verizon. So I'm going to pick that phone up on Friday and will be trying it out during the buyer's remorse period before i decide i want to switch. My question is if I transfer my sidekick number to the Droid, can I easily put it back on my sidekick and be right where i started from, same plans and rates and everything? Or else I was thinking of putting a different number on the Droid FOR NOW, and if I decide to switch then put my sidekick number over to the Droid. Which should I do and how does switching numbers between carriers work? I want to make sure if I transfer the number I'm using right now and then for some reason don't like the droid, keyboard is my big thing, then I can easily bring my number back to my sidekick without any hassle.
