For whatever one dumb old man's opinion is worth, I think iOS 5+ changed most of what we'd been complaining about with iOS.
I don't see (personally) much point in adding themes or things that do this or that to lower battery life or change the appearance and function of the device so much that you can't hand it off to another iOS person to use when necessary.
But...I still like to jailbreak for a very few items that really *do* something that iOS still does not do.
iBlacklist <--Very, very useful.
Youmail <--The jailbreak version is slightly more useful than App Store
MyWi <--For the MyWi On Demand feature to tether iPad
My3G <--Of rare use but neat when it's needed
SBSettings <--Easy toggles when it's too noisy for Siri
AutoResponder <--Polite way to ignore SMS when you're driving
SiriToggles & VoiceUtils <--We're only *beginning* to use the power of Siri!!
All this other stuff people do, making iOS very fancy with script fonts and weird backgrounds and colour, or making your iPhone look and/or act like Android...I just don't get it.

Now that I think of it, I don't even use biteSMS, which many of you seem to love.
I've tried it out, but its extra features just aren't any use to me. iMessage works just fine for me.
I can't imagine a time I'd need to compose an SMS to be sent at a later time. If people need to do that, it's great, but I can't imagine!
