I'm connected to a wifi network. I had to unlock/jailbreak it so I can use my gophone sim card with it. Now it's randomly charging me 8 or so cents, there is no new text or anything and I'm pretty sure I didn't call anyone in my sleep. I just got this iPhone from my friend last night and I'm using my own at&t sim.I don't have unlimited data yet, but I have free txting. Does anyone know what is going on? I'd prefer not to call customer support because I had to go to illegal means to unlock the phone. Thank you.
