Like you can select at boot or custom (and signed) .ipsw files that you can restore via iTunes? Because I could have done that too, but 5.1.1 was crashing for me too often, boot too long to boot, and couldn't download ANY new apps.
iOS 7 looks like crap and the UI isn't very user friendly but it boots in under 10 seconds (iOS 5.1.1 with jailbreak takes 1-2 minutes), hasn't crashed to date, and I can download any app and get updates for them as well.
Probably has a lot to do with the jailbreak...New respect for the Chinese because their iOS 7 jailbreak is obviously MUCH better than redsn0w ever was....
Yep, its easy to do with A4 devices (and I think its only possible with A4 devices and below, if I'm not mistaken)
Gives one the option to go with iOS 7 and iOS 5 and in between. I understand what you mean regarding iOS 7, I suppose if there were apps I needed I would certainly follow suit. Its much superior in that regard and if one is a heavy app user then its important to stick with ios 7.
However the apps I tend to primarily use work on iOS 5 (basic social apps, dropbox, and a few workout apps thats it - rest is music) so its not as advantageous for me.
Myself, I slightly prefer iOS 7 & 8 design over the older one (seem to be of minority opinion on that), but I find the older iOS runs a lot faster and seems to give my 4 better battery life.
Best of both worlds!
