Ok so im planning on getting the Desire HD. I plan on not getting any sort of data plan and only using wifi as data source. I'll be using PAYG.So i've been looking at some videos of setting up sense. YouTube - Droid Incredible setup Skip to 1:43. When i reach this part what should i choose? I would have gone with wifi only, but would this mean that GPRS wont work? Is GPRS part of a data plan? edit: what would be the ideal settings i should have ticked?
