Competition is a good thing so T-Mobile, not to be outdone by Verizon, is having a buy one, get one deal on their Galaxy S phone, the Samsung Vibrant. The Samsung Vibrant will be available at the two for one price with a new two year contract. The second Vibrant is free after a $50 mail-in rebate.

Also, T-Mobile announced today “Kids Are Free” family plans for their network. Anyone who signs up for a family talk plan at T-Mobile between now and November 2nd won’t have to pay the additional line fees for up to three lines after your first two. This means lines three to five are totally free. [MobileBurn]
