How much will it cost to get my iPhone fixed at Apple?

My iPhone is acting up and won't let me FaceTime and other things so how much will it cost for them to do something because a year already passed

It could be simple factory reset which is free. Or it could be something big like replacing wireless antenna, camera, etc, which can cost from 50- few hundred$$. I would just try and factory reset the phone through itunes and I bet everything will work fine.

It depends on what may need to be done to it. Of course only they would know after the fact.

$200 to $270 to replace since it is out of warranty. But they will at least try to resolve the issue through normal troublshooting. I suspect your standard reset; holding down the power and home button until the phone turns off and letting it reboot will help greatly.

The Apple reatil store will give technical help for free.

A lot more than its worth to be quite honest. At the prices they charge, if what fatefinger listed is correct, you would be better off saving up a few more bucks for a new iphone if the upgrade is available on your plan.

A factory reset could possible help you in your situation as a setting could have been messed with unintentionally. Try it and see what happens, just back up your iphone incase it doesn't so you don't lose everything permanently. If you posses the skills and tools you could try your hand at replacing or taking a look at the components on the board in the iphone. Is the camera not showing a picture or is it just not letting you connect to someone via facetime at all? If you don't get a picture than its a camera malfunction in the data line, probably 35 bucks for one on ebay. Is it not letting you connect at all? Time to look at components around the wireless antenna. Or you can google excavate a bit more and see what you come up with, best I can give you if you are not comfortable with ripping apart your phone.
