Of you jailbreak tethered you will be able to reboot, to a "none-jailbroken" state. This means everything works, calls, text, web, email.
The only thing that don't work when you reboot away from computer is Cydia, anything from Cydia, and Safari. But you can just use another browser from the AppStore. I recommend "Atomic Web Browser", "Google Search", or "Yandix Opera Mini"
