Hi @all, I`m using the iphone (hacked/unlocked US-version) with a german SIM in Germany. It works fine and I love this device. I`ve detected one problem during daily business. SMS with a text-originator (e.g. using for monitoring-notifications) are blocked by the iphone. It means that I could received a message from "+00000" or any other numbers but not from for example with originator "Thorsten". Is that only a problem with an unlocked iphone and it works with an original AT&T-sim? Thanks for your answers/support.
