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.

Help please?

I ended up erasing the laptop's HD and then upgraded to 10.6. So far haven't had any issues, although I'd love if someone could tell me how to stop iTunes from opening up everytime I plug my phone in to charge. Tried both iTunes, system and user (although I'm the only one) preferences.

Thanks!

If it worked on the PC but not on some of your wall or car chargers my gut feeling tells me that it is a hardware problem, but not the hardware on your phone. Some of these chargers are horrific and are actually capable of ruining your phone/battery. If you spend $$$ on a phone why try to go the cheap route on a charger.

It's an apple charger, they all are except the car charger.

Brownbailey, I did not mean you singular but you plural. So not you specifically. sorry about that and I most certainly did not mean to offend you. I am still puzzled by the fact that it works on a PC but nothing else. may be some issues with the Mac. Again I do not think that it is your phone that has issues.

Ah. Well still, it did work on a mac, and works on one pc but not another. Works on my parents Mac, but only from the computer directly and not from the external 4-port hub (which makes sense, but figured I'd add in case it is relevant).

Yes that is relevant. Apparently some of the front USB's as well as Hubs do not supply enough amperage. It is always recommended to use the USB port in the back and/or right of the computers motherboard. I do not think that the problem is with your iPhone. you might try to re-install iTunes on the computers where your iPhone does not work on and see if tat makes a difference. Also check the version of itunes that works. There are some difference in some of the version and they can cause some problems with it as well.
