Am i likely to receive another 3g, or will i get a newer model due to the unavailability of this older model?.
If anyone knows how much money i would be likely to receive thought insurance? that would earn you a best answer
If they can't get you the original, you will get a phone of a similar level. It won't be an phone4 because you are only insured 'like for like' not 'better than'.
The terms and conditions of the insurance must have the rules for such conditions but I think that It would be claimable but of the same level or price product.
