No Wifi, No Carrier, only powers on w. plugged in, reboots constantly
The issue began like this: this iphone 3gs 16 gb black with IOS 4.1 was working like a charm until one day it was running low on battery (10%) and I plugged in to the wall for charge.
The next day the phone was turn off. After turning it on (taking longer than usual), the battery icon was full charged. There is no carrier, the wi-fi and bluetooth was grayed out, and there is no sound at all, no even when playing a song in the ipod. It remains like this for like 2 minutes, and continue rebooting itself.
All of this happens with the phone connected to wall. When i unplug it, immediately turns off, and doesn't power on unless i connect it again.
If the phone is connected to the PC doesn't get to the main screen, starting to reboot again and again.
If its plugged to the PC and gets on DFU, the PC detects it but Itunes can't restore it (since during the process the phone shutdown and reboots). I can take it out of DFU with tinyumbrella.
I tried replacing the battery for a new one with no success, the symptoms remains the same.
I know of other guy who had the same issue the same day (on Feb 2012). That guy took his iPhone to other technician but didn't have a answer for this. I find that other guy had this same issue and posted a question on other forum but didn't receive any feedback there.
If anyone has any comments on such a weird problem I'll really appreciate that. Also this may be a warning to anyone thinking on getting a used phone like this one. I'm at the point that the last thing I can do is sale this phone as parts.
Thanks in advance!

Thanks for your responses. I tried one more thing just for curiosity, i removed the battery, reassembled it again and the symptoms remains the same.
Did anyone tried removing the battery and turn it on again? Because my strongest feeling is that the motherboard is somehow damaged and if someone didn't experience this kind of behavior when removing the battery this may clearly indicate a problem in some other area like the MB.

You did" remove the battery and turned it on" by plugging it in a USB port or AC adapter?

I plugged it to the AC adapter, and it worked with the same symptoms as before. I didn't try with the USB, i'll do that later today. Maybe it will stay on if it is DFU (since it should consume less power i think).
By the way the USB cable is in great shape, and I also cleaned the iphone dock just to be sure, it was ok anyway.
