Thanks OldTurkey, much appreciated. I'll swap the battery 1st and then look into the fuses and report back. Regards

Sounds good and all the best to you.

Right guys, the battery arrived and as expected it made no diffrence whatsover. So I got my microscope out and closely inspected all the fuses outlined in the images above. One looks as if its alot darker than all the others around it (highlighted on the image), could this be causing the problem ? if so is there any way of bridging it with a blob of solder or is that going to cause more problems....15w Soldering iron at the ready :) so any help will be appreciated.

get the multimeter out and see whether you have continuity/resistance on that fuse. A blob of solder will sort it out most easiest of all the solutions to fix it. Did you look at the pins on the connector 4?

by

Pins look fine on the connector Pollytintop, sits really flush on the motherboard too. Im not fimiliar with the fuses so would you say the one I pointed out could be the problem, and if so do I just plonk a blob of solder on top of it or do I pair it to another one.

Wurzel, check on your fuses and make sure that they are okay. I attached a few images I have for so it gives you an idea of where to check. you can also download the schematic for the iPhone from here hope that this will at least get you started. Of course, make sure that you change your battery first and that you have a battery appropriate for the 3G. Good Luck

Thanks for reminding me, to many pics bad labeling ;-)

Lets just say the new battery doesn't solve the issue, can I bridge the fuse with a bit of wire (simular way to a Nintendo DS ?) or is that a big NO NO ??

by

Yes you could, BUT remember that you would now have an unprotected circuit. If anything is still causing a short circuit.......:-)

by

Nothing much to lose really, worst thing was I was managing OK with a slow charge and using the phone daily, thought reseting the phone back to factory settings might do the trick but forgot that I needed to connect to itunes to activate the phone :(, can't jailbreak it because the PC won't reconise it so im stuck really. I'll wait for the new battery and if that's no good I'll bridge the fuse and let you know, thanks for your help and quick responses. Great Website.
