Hi all, Long time browser, first post. Just looking for some advice based on the following scenario: I purchased a refurbished iPad 64gb 3G model. Had a screen protector on from day one. The edges started lifting so I decided to take I off and use the device naked. I then noticed a tiny, and I mean tiny nick in the glass on the top side of the iPad. It's actually on the black border about 3mm from the screen but there is a 4mm hairline scratch that does extend on to the edge of the screen proper. So I called Apple care to see what, if anything they can do. Amazingly they are going to replace (and tech support did say it would be a different unit) under warranty. Here's the kicker. I am running untethered Jailbreak on 4.3.3. I purely use jail breaking for the incredible added functionality you get from some of the Cydia apps. Some of these apps add so much functionality to the iPad it's unbelievable. I received an email from Apple today with instructions on returning the iPad and it states quite clearly that they will update the OS to 4.3.5. On the replacement unit. Now I know 4.3.5 has been jail broken BUT its tethered and that's looking unlikely to change. So, do I get the replacement and live with a tethered jailbreak? Or do I suck it up and live with the tiny mark in the glass? I'm a bit anal about my stuff being perfect! Plus, I just like the thought of the untethered jailbreak. I rarely have to reboot but still..... I have seen two threads on another forum about how to roll back to 4.3.3 without blobs but am unsure how well it works. Any and all advice would be much appreciated.
