When you show up to pick up your permit to hike, and if you ask, you will probably be surprised to learn that you could pick up a no-show Whitney permit.
Two bear canisters should be enough. If not, it is ok to hang the extra in the area you are hiking. Be sure to re-bag all the food in zip-locks. Those foil freeze-dried bags take way too much space.
A PLB can only be used in an emergency. Look at a SPOT or DeLorme unit that can send out regular locations, etc. Iphones will not connect where you are going. They only work from a few spots on the Whitney summit.
Rain jacket/pants: Check the forecast when you go. Leave them home if you are taking a tent, unless foul weather is forecast. Early July if mostly dry.
