So, my boss decides to switch to Sprint and calls me on my day off on his way to the Sprint store asking what phone to get. Reluctantly (he's not the most technically proficient), we end up agreeing that he should get a Treo 600 like mine. I tell him to ask the Sprint Store person what other phones have IM capability, thinking they can't mess up that question. Sure enough, he calls me while he's in the store to tell me the guy says that the i500 can do IM, but the Treo 600 can't. Sigh...
