How would a bluetooth internet connection via your mobile phone save any energy at all? It would drain your phones battery in no time. Where I live you can get multiple SIM cards for one contract.

I believe there are more SKU's in upcoming months with Intel Atom. I believe in 2010, Nokia will exclusively ordering microprocessors from Intel only.

Built-in SIM?

How about blue-tooth to connect to my phone with my SIM? This would save battery power & I wouldn't have to have 2 phone/data accounts. No way I am going to pay for 2 unlimited data accounts unless 2nd one is free!
