Feasible to upgrade processor in iPhone 4?
I have a cracked iphone 4, and I plan to replace the front display and back panel. The iphone 6 recently came out, and I have little interest in spending the money to replace my phone, but I wouldn't mind upgrading the processor in my 4 if possible. I can't find much on the subject, but I wonder how difficult it might be to replace the A4 processor. Would an A8 processor be compatible? Is the chip socketed or soldered? What kinds of tools might I need if I wanted to attempt to do this? Thanks!
