Iphone 3GS making 2 phones into 1

[sihiggs79]

Hi.

I have an iphone 3GS with a smashed screen, and a 3GS with IMEI blocked (reported it lost months ago then found it in sons toy box). How can I combine the 2 phones to make one working one? I have taken the phones apart before but just wanted to check with parts need to put into the unsmashed phone. Thank you

Put the blocked one's screen onto the one with the smashed screen. The blocked IMEI is totally useless inside the US except for the screen and some other parts.
