I am planning to buy the Nexus S unlocked. I was wondering how much money I would save buying the phone unlocked compared to signing a two year contract with T-Mobile?
There is a $20/month difference between the contract and no contract plans (Even More vs. Even More Plus respectively). So $20 x 24 months = $480 in savings on the no contract (Even More Plus) plan.
Buying the Nexus S unsubsidized will cost you more up front, but will actually save you money over 2 years.
With Contract: $199 + $20x24months = $679
No Contract: $529 - That's $150 in savings
