It's second hand and I only have the receipt for this and not the "original" receipt.

How would the service center know the difference between these receipts. Would they know that it's second hand?

If not, then I'll send it in!!

On my receipt, there's an IMEI number, so they can tell the receipt and phone match....

Cheers!


Ps. If I do decide to send it in, should Ireflash the phone with it's original firmware?
