Does the touch 4G use a different size dock connector or something? I bought a cheap cable off amazon from the OEM shop and it appeared to be exactly like the official apple cable right down to the exact markings but the connector would not fit in the slot, the metal part is too large. I am getting a refund from the company I bought it from but I was wondering if anyone knows of a cheap source for cables that fit in the dock connector of the 4G touch.
