T-Mobile USA is expected to layout later today its new plans to sell the iPhone and other smartphones on an unsubsidized basis with no-contract, unlimited data plans.
Currently, the new Samsung Galaxy S II is selling for $413.99 at the company's web site. The Galaxy S can be purchased for a $29.99 down payment and $16 per month for 24 months.
The company's website also lists two other plans for unlimited talk and text, but with high-speed data limited to either 500 MB for $50 a month or an added 2GB for $60 a month. There is no contract and no early termination fee.
T-Mobile's event begins at 11:30 a.m. ET today.
