Hi. I bought a Samsung Evergreen from a Koodo kiosk and have been with Koodo for the last three years. I recently moved to California and signed up for AT&T. My phone background screen says AT&T, and I can access all of my AT&T plan's features, but my phone still shows the Koodo screen when I turn the phone on or off. Does this mean I am not completely unlocked or that I haven't completely cancelled my Koodo account? I got the unlock number and gave it to the AT&T guy but I don't know if he did anything with it... could this be the problem? Thanks!!
