Help me please...

week ago win pwned iphone, worked well, updated with cydia, error 1 occured which was a message saying "this accessory is not ment to work with iphone"

but nothing was pluged in, had little battery when i got home and tried to sync and it didnt detect iphone on itunes nor did it light up or charge the iphone. so not being able to restore it on itunes i tried to reset and erase all data from general settings and over half way through the phone died out.

i reconnected it to the pc laptop and error 2 occured it was charging or at least drawing temp power from the usb cord but still not being detected, then when i tried to turn the iphone back it went in a cycle of winpwn logo then no winpwn logo (which is all it does now)

i dont know how to restore the phone now, i tried win pwn, and quick pwn but like itunes nothing detects the iphone (and yes i tried dfu mode and other restore mode)

i cant take the phone to apple cos its 2g and in australia apple only sells 3g and wont service 2g.

Can someone please help me. This may be a hardware problem with a boot error or just a boot and firmware corruption but how would i fix this by myself with prompts or be able to pay for repairs in sydney.
