is the 9700 blackberry from Walmart able to be unlocked
Yes.
PS. To the OP, did you drop it in water, have it run over or smashed out of anger? If none of those three occurred, did it turn into a paperweight? Have you tried everything offered on Crackberry's HowTo section to fix it?

Depending on location, tryout your local Craigslist or Kijiji. They sell from anywhere from $200-$300 if you are going to pay more than $300, your paying too much for a second hand item. If you cannot find them in your local classifieds , your next option is to go on Ebay or the marketplace on Crackberry.
