Motorola RAZR V3c

I've read a few posts talking about software versions .02 or .03 etc. I am looking at getting a Razor off of Ebay and was wondering if the phone I purchase will be able to be updated with the newest software at a Verizon store. I'm not familiar with a lot of the technical stuff when it comes to phones.... I just want the Razor and I want to make sure it works... Any info would help - thanks!
