I am using my unlocked iPhone with Vodafone....and on the top right side of the screen I have the battery icon..next to that the bluetooth icon...but next to that I have a picture of a telephone receiver with 7 little dots (I assume to represent buttons) below it. I just wondered what this meant..anyone know? It's there all the time even when the phone is not in standby mode. I thought maybe it meant that the phone line was in use or the sim perhaps. Just trying to cover myself from getting hit with a huge cell phone bill.
Would love to know. Sorry for the many fundamental questions.
