Are iphone 4 and iphone 4s lcd and digitizers the same?

If i get a iphone 4s front panel. Like the lcd and digitizer, like i'm talkking the front panel haha. Will it work in a iphone 4?

No, they are different. In iphone 4 careers have different digitizers. The connectors will fit but the it won't work either way. The parts are physically different including the sensors as well as home button. However, it is possible to work but it can be done only by specialists as it is a hard and delicate procedure. I suggest you buy a new digitizer, they aren't that expensive and you can purchase them on ebay.
