logic board of my old iPhone 4 8gb into a new iPhone 4 8gb

relating to this, if i put the logic board of my old iphone 4 8gb into a new iphone 4 8gb, would it boot up my phone in the exact same way, and basically be the same phone?

Is this a good question?

Just so we understand your question here: You have two exact same iPhone 4 phones. One works tho other doesn't, the one that works case is in tough shape. So you want to move the logic board of the working phone to the better case, but broken phone. If that is what you are facing that could be done.


basically i attempted to replace the screen of my iphone 4 but messed up meaning that i can't repair that phone. However, the phone was working perfectly before i attempted the screen replacement, but because i did it incorrectly i can't put it back together. In this case, if i ordered a new iphone 4, could i remove the logic board and replace it with the logic board of my old phone, and if i did would it run the phone like how my old phone ran? ie photos messages apps etc etc

Thanks for your reply, did not see it until now

I agree with jessabethany here it would be cheaper fixing your phone than trying to thrasher the guts to a new phone. Besides, I think you'll find this will be harder that messing up the screen.

As to getting off your stuff, I haven't tried this but this makes sense:

Disconnect the display and using the sync cable connect your phone to a Mac/PC running iTunes. It should be visible that way. Then copy it back on to your new iPhone or to have in case it gets lost in fixing.

The logic board "IS" the phone. So yes, your logic board in any other housing would act like your phone.


What do you mean you 'messed up' the first phone. If the logic board is okay, then just replace whatever piece is 'messed up' rather than buying a new phone, no?
