Can the Apple Store Know If An iPhone Has Been Jailbroken?

So the other day I was kind of pressured by a mate to jailbreak my iPhone. Stupid I know. Right after I did It, It was laggy, unresponsive and I found it kind of glitchy so I used the 'Reset' feature in the settings and after about an hour, i noticed it was stuck on the Apple logo loop until It died. I can't put it into DFU mode or Restore mode. I've used both before so i knew what I was doing but to no avail.

So tomorrow I plan on going to the Apple store to see if I can get it fixed. I knew that jail breaking the iPhone voided the warranty so I'm wondering If they are able to know if its been Jail broken? I'm kind of worried I'd not be able to get it fixed because the phone didn't fully restore and is stuck on the loop.

Yes they will Know if it has not been restored to stock. I have had a few problems with my phone, (its out of warranty now) but once you jailbreak you void the warranty on it and most Apple stores will not look at it for you.

What did you use to Jailbreak it with? What Firmware are you running and are you using a mac or windows?

I'm sure they can tell if a phone has ever been jailbroken, even if you restore it to factory settings, but it doesn't matter. If it's stuck at the boot logo and under warranty, they'll most likely still replace it. Try troubleshooting the restoring process first, though.

For future reference, never use the "Erase All Content and Settings" feature when jailbroken; it usually leads to it getting stuck at the boot logo. Just hit the restore button in iTunes (instead of resetting on the phone itself). It serves the same purpose.

I recommend that you keep trying to get it into DFU mode. It should restore just fine if you can get iTunes to recognize it. Try rebooting the computer first. If that doesn't work, try restoring on another computer.

I took my phone into the store with a cracked screen. It was still jailbroken. They still replaced the phone but warned me that they were not supposed to.

Your mileage may vary.

Does this mean if you are using MobileMe and attempt to do a remote Erase in the event the phone is lost or stolen that it won't work?

No. It will work. It wouldn't matter if it got locked at the boot logo while remotely erasing the data. It would need to be restored before it could be used again.

How would they be able to tell if you restore to factory settings?

I'm sure they can tell if they really wanted to know. I think it permanently changes some files that survive a restore to factory settings and mark it as a previously jailbroken device. However, like I said, it doesn't matter. They don't care or waste time looking that closely. I'm just saying that if they wanted to, they could. If you restore it to factory settings, you'll get a replacement. If it's jailbroken and stuck at the boot logo, you'll get a replacement. If the screen is cracked, you'll almost certainly get a free replacement (first occurrence).

They do this because their customer service is exceptional, not because they can't tell. They aren't going to refuse to replace a phone that is under warranty and stuck at the boot logo, regardless if it was jailbroken or not.

If its stuck on Apple logo and they get it back up and running there and then, as long as you're on stock and there is no trace of your phone having been jailbroken they can't tell.
