Ive confirmed this at the San Francisco, Sacramento, and Irvine Apple store. Apples jailbreaking policy is no longer "JB and the warranty is voided" its basically now "Apple needs to prove JB is causing the error" So I took my iPhone 6 (fully themed and jailbroken) in 3 times at these stores (all together, not each) because my front camera is moving. The genius did not care one bit about the JB, bc a JB cannot cause the front camera to move. So this could be good news. Just prove the JB did not cause whatever you are taking your phone in for.
