I have unlimited data on my current iPhone 4 on verizon so I'm not in too much of a rush since there's no jailbreak yet for the 6, where I would be able to finally take advantage of the 4G LTE without being throttled. Even still with this 4, I tether all day long to my iPad and/or MacBook. I don't personally have a particular method or practice when it comes to tethering off of my 4 because the battery is so old it's practically connected at most times since it depletes from 100% to 0 in about 3-4 hours with constant use. Standy on the 4 for me is about a day perhaps. But that's cause this is considered an old phone now.
