I think we all knew that there would be some changes to the iPhone 4 CDMA model (besides the obvious chip differences). Well, it seems that technology comes at a cost. In a recent teardown and cost analysis, iSuppli says the new iPhone 4 is cheaper to manufacture than the GSM model.

The latest version of the iPhone 4 carries a BOM of $171.35, down from $187.51 for the previous model, based on a preliminary pricing estimate issued in June. When manufacturing expenses are added, the total production cost for the CDMA iPhone 4 amounts to $178.45.
