So I had my nexus s 4g fully flashed by some cricket store here in San Antonio, Texas. Everything was working fine till I messed around with QPST to flash a new PRL. I messed up all my settings and had to flash the phone all over again. I got everything working with all the guides here and with some help by Chris(with my MID).

So now I got text messaging, mms, and internet and calls in, but I can't call out.. I don't know how to fix this. It doesn't let me call out at all. Not even to 611 or to *228.. Is there a setting I missed in QPST. I had this problem before with an EVO 4G so that's why I got this Nexus S. Does anyone know how to fix this? Please help..
