T-Mobile is having its Valentines Day sale today. This offer allows Classic And Value plan subscribers to get any 4G smartphone, as well as some 4G tablets, for free after a mail-in rebate.

Just remember that HSPA+42 devices ( HTC Amaze 4G and Samsung Galaxy S II) will require a 5 GB data plan. Other than that, you are in the clear for your brand new 4G devices.
