What's the point of the extra SIM card? Doesn't let you use 2 carriers at 1 time? If so, why would you want to do that?
It would be great if you extra SIM card was there just to provide extra storage. Especially if that extra storage was internal storage.
I don't think you'll get 4 with this unit in the US.

On these dual SIM phones must the 2 SIM cards be for the same protocall (CDMA / GSM) for example 2 GSM SIM cards or 2 CDMA SIM cards.
OR
Will newer phones like the Samsung Galaxy Note 2 work with one GSM and one CDMA SIM card at the same time?
For example:
- Rogers GSM SIM for Canada and Verizon CDMA SIM for the USA
- Bell CDMA SIM for Canada and ATT GSM SIM for the USA
