It is possible. The thing to consider is the layout of the motherboard from different carriers can vary. So for example, if you try putting a Verizon motherboard in a T-Mobile phone it will not fit correctly in the midframe where the motherboard sits due to the different layout of components on the motherboard. The motherboards themselves are the same shape and size so a person can grind down the high areas of the midframe to be able to fit another carriers motherboard in the midframe. I have done this before with a Dremel. Not the funnest task but it can be done if you do not feel like purchasing parts. The screens themselves are not carrier specific so no worries there. It's just a matter of getting another carriers motherboard to fit properly it the midframe. So you can grind down the midframe if needed or you can also buy or locate a carrier specific midframe to match the motherboard you want to use.
