I don't believe 1) purplesn0w will work and 2) having both installed is a good idea.

Uninstall both, do a hard reset, reinstall just ultrasn0w, reboot, and then wait. It may take up to 30 minutes to pick signal up.

^ What i.Annie said but also, from what I remember when I was using iphone with Go phone service was that you have to get a new Go phone SIM from AT&T and have them activate service on it before you put it into a phone so that it doesn't become attached to that phones IMEI. I just went into an ATT store and said I broke my SIM card and dont have my go phone with me and they gave me a new SIM. Then when I got home called ATT and told them the new SIM number. They will ask you to put the new SIM in your go phone, just say its at a friends house/you dont have it right then so that way your new SIM is not tied to your crappy go phone. (This workaround is normally for phones locked to ATT but is an option if you cant get your service working with an unlock)
