I have a 2G iPhone with 2.1 (unlocked+jalibroken) and a weird problem..
I changed my usual SIM (movistar) for one from another carrier (Orange).
Switched back to my SIM and my iPhone keeps teeling i'm on Orange network! Everything works so i'm really in movistar network.
Tried to restore, reset settings, nothing works.
FYI the CarrierBundle.Bundle points to the correct network with my custom logos but they never show up anymore.
