Last friday I have noticed a small change in how iPhone shows the network. There is no longer “Orange” displayed, as it was for the last 2 years. Now it says “PL OPL”. OPL as in Orange Poland I suppose.
Curiosity requires me to check if this was operator related change or Apple changed iPhone’s carrier XML file.
FIX: Unfortunately it happened two times so far (running iOS 4.2.1 on iPhone 3G) and the only working fix is to Restore the iPhone from backup. It works, but takes some time.
