I normally just browse these forums, but a few hours googling around has compelled me to create this account and canvas some well-informed views on the following. Having just bought an iphone 5s, I realise just how clunky ios7 had made my old iphone 4. My dad is inheriting my iphone 4, and I'm concerned he will not get on with it now it's all bunged up. Unfortunately, as I have never had any interest in jailbreaking my phone, I don't have any blobs available to do a downgrade (in fact I never used ios6 - no features I wanted). What I'd really like to know is if people think there is (or is not) likely to be a way to downgrade a jailbroken iphone 4, and why? I know apple aren't signing older versions of ios, but as I (mis?)understand things a jailbroken phone could open a path around this issue...? I know this is ultimately my own fault for upgrading too quickly - I thought the swipe up menu was useful, and assumed apple weren't going to do anything malicious to force people to upgrade their hardware (whoops!).
