Does anybody here still jailbreak these days?

[tenders]

I used to love jailbreaking, especially for the Wi-Fi-to-Bluetooth hotspot capability, but stopped doing it when Apple incorporated most of the best ideas into the OS (though not that one).

Plus, my company put its proprietary email app onto iOS, and out of security concerns it requires a non-jailbroken system to run.

There are a lot of innovative ideas in those jailbreaks you linked to, but none that would provide a return on the investment of time and hassle involved in jailbreaking.
