I have had my Iphone for the last month and just JB'ed this weekend (come from WebOS where I homebrewed). My wife is deathly afraid of if something happens to my phone and I have to take it in. Yes, I am aware the JB voids the warranty but I was curious as to any discretion the Apple Store people have in terms of honoring the warranty with a JB?? Another question, I backed up via ITunes before the JB on my IMac but cant find it anywhere; where is the back-up located? And if I backed up after a JB, does it override the pre-JB back-up?? thanks for any answers!!
