No one is saying the outsourcing is good or bad but its normal across the industry. This is a technical point but what I said is true in my last post is true.
This is similar to the GSM vs. CDMA iPhone 4 - different revisions of the same phone. In that case its the same exact processor with the same exact SoC design. The radio system design does lead to significant differences - both hardware and network based - no SIM, no simultaneous data/voice (CDMA/Verizon network is capable of this on other phones BTW), different system board revision, minor button placement and exterior design differences, better antenna design (no antennagate grip reception problem), lower max data transfer rate (due to CDMA network but Verizon's real world speeds are better), voice conferencing limited to two callers, no call hold, manually set call settings (call forward, call waiting and caller id), and the hotspot feature is available on Verizon (not a technical limitation).
