Previous rumors have now materialized, with T-Mobile offering nearly all Samsung devices for free on contract over the coming weekend. November 16-17 will see the US telco offering sales on pretty much every Samsung device on offer for $0 on contract.
The savings will come in the form of a mail-in rebate, meaning that if you were looking to grab a Samsung Galaxy S III on a Class Plan, you will still have to dump $299 down onto the counter, but you'll get a $299 mail-in rebate in return - not bad at all, but not the best considering you still have to cough up the cash first.
There is a phone missing here, which is the Galaxy Note II, but considering the phone just launched and that T-Mobile's on-contract price is still very expensive, it makes sense. A Galaxy S III for $0 on-contract is pretty good, and you can't complain about that.
