I got great help last time, so I'm trying you guys again. I am running Win7 x64. Problem 1: I have a jailbroken iPhone 3GS running 3.1.2 (think it only has 3.1.2 shsh blobs saved, but not sure. Going to run TinyUmbrella to see). I want to update to 4.1 and jailbreak. 1. Is there a way to update to 4.1 and jailbreak it, while still keeping it unlockable in the future? 2. Is this process correct for updating to 4.1 and jailbreaking it? a) Run TinyUmbrella to save SHSH blobs. b) Update to 4.1 using custom firmware (where do I download this? I assume it's not http://www.felixbruns.de/iPod/firmware/ since this is from Apple's servers?) c) Run limera1n. Problem 2: I have a jailbroken iPhone 4 running 4.0.1. I want to update to 4.1 and jailbreak. 1. Do I just follow these instructions if I want to keep it unlockable in the future? http://www.iclarified.com/entry/index.php?enid=12133 2. If I have Appsync, and I update to 4.1 and jailbreak, will I be able to sync all my current apps back to my iPhone after jailbreaking? Thanks again for all the help.
