Hey everyone, I've been searching around and I could not find these answers if anyone can help. iphone: 3GS version: 4.0.2 jailbroken w/ limera1n baseband: 5.13.04 I just recently jailbroken with limera1n and installed cydia on my 3GS. And I tried to use tinyumbrella to save the version 4.0.2 but I don't think the request was sent to cydia since Apple stopped signing 4.0.2. So I was wondering if there is any benefits of sticking to 4.0.2 now? Since 4.1 is out with the same jailbreak. If I do upgrade to 4.1, do I upgrade through this? http://www.felixbruns.de/iPod/firmware/ Also if I upgrade to 4.1, will my baseband change? If it does, what will happen? Because the unlock for 4.1 is not out yet and I read up on some forum or thread that unlocking is based on your baseband. Also for the SHSH blobs, where do you get the information of when Apple stops signing a certain version? And how do you know if Cydia had received your request through TinyUmbrella? For example, when I used tinyumbrella for 4.0.2, (this was when 4.1 was out but I did not know whether they had stopped signing 4.0.2 yet or not) it shows this: All saved SHSHs: iPhone3GS 4.1 (and then some #s and letters) What does this mean? On the Log, it does not mention that my SHSH were requested from Cydia. Also when you jailbreak your Iphone, can you still download apps from the official Apple App Store? Do you have to have the latest update (both iphone and itunes) in order to download from it? Thanks for the help!
