T-Mobile is offering $0 Down for many of its leading smartphones, including popular favorites like the GS4 and the iPhone 5, as well as others.  These are the lowest up front prices we've seen in many cases, and in most instances also results in a notably lower net cost even after all phone payments are made.  Requires a 24 month phone payment plan but no contract.  These are some of the best deals we have seen direct from carrier.
