Hey Marc, what happens if you take out the turbosim card? Does it work like that?
You need to know that people have various problems with sim cards including, loss of signal, no 3G etc. I had some problems with my iphone and some sim cards. Basically no one can guarantee that the unlock sim card will work perfectly for you. I have tried gevey,yessim and some other cards and didn't have luck. I had various problems. Later I've found this site and after thorough discussion with their support I bought their
sim card and was pleased with the results.
And don't worry, you will become tech savvy if you continue using iphones.
