Apparently, Cricket does not support five digit codes. In fact, I read a post from about eight months ago, when a customer contacted Cricket to ask about making their phones Twitter-friendly. At that time, they did not know who the customer was talking about. Well, eight months later and they still do not have a friendly relationship.
