Problem with cable or phone?
My 16Gb 3G (model A1241)phone will not charge (or recognize) certain adapters. It is currently jailbroken and unlocked using 4.2.1 on baseband 06.15.00.
It never recognized my car charger. It was charging and syncing on my usb on both my mac and pc in all ports. My friend has 2 wall adapters, one worked, the other didn't, and wouldn't acknowledge the usb connection to his pc. Last night I had the phone plugged into my mac to charge. This morning was at 50% battery, so I restarted the phone. It didn't recognize the mac, so I restarted the computer, still didn't recognize in either port.
Tried over on the pc, and it works and was able to charge to 100%.
Is this a software or hardware problem? I'm able to use all the ports with other things, my friend's adapters both work for him, as does his usb cable. I don't think it's dirt or bent pins, because I've taken it from one computer to the other without unplugging the cable from the phone, and it didn't work in one but did on the other, and I didn't shift or wiggle the connection.
