3G Yellowsn0w'd charging problems

I have a new 3G, did all the PWN, Yellowsn0w etc ... unlocked etc etc
Absolutely great!! Many thanks!
... BUT .... now the phone won't charge from either the Apple charger nor car dock. Works OK from charge on laptop. But thats not always convenient.


Anyone had this issue?
Any thoughts?

Many thanks!

..... to be clear, when I attach a device like car play or charger I get a yellow exclamation mark warning signal and message this device does not support ...
