Hello

Try the simple stuff first...make sure your USB cable that hopefully came with the 3G iPhone is original and in good order....can it be tried with another iDevice you have or can borrow..?

borrow one.the iPod shuffle 4th gen works fine I can sync it perfectly.Any more advices?

Run iTunes and connect your iPhone...place iPhone in DFU mode(use YouTube for more info) ....see if your iPhone is connected ....if all is good...Restore to the latest firmware 4.2.1
