I have a jailbroken iPhone4 (Verizon) running 4.2.8. I'm having issues with my home button not working all the time. Before I take my phone into Apple I know, I need to restore. My question is.. If Apple swaps out my phone for a new one, will I be able to jailbreak the new one? I have saved all my blobs on the cydia server and also backed up using tiny umbrella.
