I have a BlackBerry Curve 8530 that was on Sprint. I now have Straight Talk as my provider. I want use my Blackberry Curve with my Straight Talk. They are both CDMA. I purchased the MSL code and did the required steps to swap the phone. It reset but was not successful. I contacted the company that I purchased my MSL from, they said it was possible to do but I needed to contact Straight Talk and get my MSIN. (Mobile Station Identification Number). I called Straight Talk and talked to several different reps and not one of them nor their supervisor new what I was looking for. Can anyone help me accomplish swapping the phone? Any information is hugely appreciated!!
