I'm trying to update my mum's iPhone 4 which is running at 4.1. I've been trying to restore it because my mum doesn't want it to be jailbroken. I know jailbreaking is a necessity but she just doesn't want it (when she was on a trip her iPhone crashed so she visited the nearest Apple Store and they found out it was jailbroken). When I try to restore it, this message pops up: The iPhone could not be restored. This device isn't eligible for the requested build. I'm not that knowledgeable with things beyong Cydia. I checked the saved SHSH blobs and they are: 4.1, 4.2.1 and 4.2b3. Am I missing something? I've also got an iPhone myself but I'm waiting for an untethered 4.3 jailbreak. I've also got the same saved SHSH blobs. Does this mean I won't be able to update to 4.3 soon? The only difference is that my iPhone is running on firmware 4.2.1. Would appreciate all the help. Thanks!
