A Verizon employee recently remarked that the Storm was, perhaps, the worst phone Verizon has ever carried. The Storm 2 was created to fix the problems that arose with the Storm.
they have different sensors under the screens. the storm 1 only has one right in the middle so sometimes if you click a button in the corner it wont register. the storm 2 has 4 as well as a faster proccessor and wifi capability
