The iphone 4 uses a PH-AS-IP-00001 and the 3GS a IC 109B. They are two different beasts, and as you already mentioned different dimensions. I am all for fixing things, but in this case I would invest $10 and get the proper IC and coil and not risking a destroyed logic board. Just my 2 cents, good luck.
