I brought my iphone 4 on ebay recently, can I still get insurance?

I'm struggling to find insurance for my new (second-hand) iphone which my sister bought for me on ebay. I technically have proof of purchase but don't know how old it is and many places don't insure phones brought through online auction.

Can anyone suggest an insurer that will insure regardless of age/method of purchase?

Yes, you can always get insurance on anything.
