I purchased an S2X around Christmas (love it) and wanted to unlock it (just because I don't like having my phones locked, I have no plans to leave Koodo though, that's for sure!). Before sending for a code, I wanted to confirm the unlock screen would come up as expected when another non-Koodo or non-TELUS SIM card is inserted. However, when I put in a SpeakOut SIM (which I believe works on the Rogers network), it works fine. No unlock screen shows up. It recognizes the SpeakOut network in the status bar, and I can even make and receive calls to my SpeakOut number, no problem. I'm not complaining, but I am confused.
