Hi Smiddy - just saw your comment to me. How you pronounce the name of the God of Abraham depends on phonetics. For instance the name John, Ian, Jan, Evan, Ivan are all the same name. I think the J or Y issue comes in due to the German/English translations. Ju or Yu are very similar. Regarding V or W - the W in German is actually V.
In English if you say O, you can hear the W. Maybe in German the sound is OV.
When I've heard some rabbis pronounce the W in Hebrew I've hear them use the V sound rather than W.
On the subject of phonetics Ts can become Ds. Bs can become Vs, Ks can become Gs etc.
But the identity of the God of Abraham remains the same however you pronounce His name.
