    How many cycles does a typical iPhone 4 battery have before it needs replacing? And how much faster do you suppose you spend your battery's lifespan by tethering using miwi?

    Well, I don't know about the first part of your question, but as for the MyWi, it depends on your configuration.

    For instance, I turn the pulsing blue bar off and drop the strength to about 30% and I find the battery drains about 12% an hour.
    Usually, I connect my phone to my MacBook so that it stays charged while I'm tethering. It doesn't drain the MacBook battery as much as running it alone drains the phone's battery.
