just saw this I haven't from Redmond Pie checked further. says it's for 5.0.1 with basebands 1.0.11, 1.0.13 And 1.0.14 expected dispatch dates between the 3rd and 7th March. As always, due to the relatively high price tag (currently showing a pre order price of $54.99) associated with this unlock solution we would recommend exercising extreme caution when purchasing or waiting until the unlock has been proven to work for the masses.
