I'm probably asking a stupid question, but want to be certain before I go through the effort only to find out there was something I missed. My current 5 has a few issues (bent frame, faulty camera, cracked screen) that have made it almost unbearable to use. It's running 6.1 and is jailbroken just the way I like it. I just bought a used 5 running 7.x and I thought that rather than losing my current setup, I could swap logic boards and put my sim in the new phone instead. If I do, 1) would that work to maintain functionality, and 2) would I still need to activate the new phone? I don't mean to be rude, but please don't preach to me about how hard/unnecessary/etc that would be. I have many other reasons that are strongly motivating me to consider doing this in the first place that I'm just not going to get into. I just want to know if its possible, and be aware of any pitfalls that may lie in wait. Thanks!
