hmmm since noone answer this, i will.

if the warranty card is unfilled. here is the tips to workaround to get the warranty working properly.

first of all, sony service centre (SSC) requires u to have an official reciept of the AUTHORISED shop u brought from to be able to send in for warranty service. unauthorised shop usually, u send it back to the shop, the shop to the supplier, and supplier to the backdoor SSC. but if u already register it in sonystyle, ur unit able to go in front door

the date will be refer to your official reciept+filled warranty card and sonystyle registration (make sure it match).

what u need to do to work around it is, (for unfilled and unregister unit, with or without reciept,...)
1. if u dont have the reciept
2. unfilled warranty card.
3. not registered online with sonysytle/mysony. (with all this, u can basically throw away the reciept)

let say ur camera was damange today.
1. go register ur gear in mysony/style.
2. during registration, when there is a column where it ask, where u get ur item from, pick, "GIFT" (so u wont have receipt! yay)
3. pick a buy date, maybe a week before (so u still eligible for the additional +3 month warranty)
4. then wait for a month, (dont send ur camera instantly, they will smell something fishy... wait for a few month)
5. email to sonystyle, they mostly will pass ur mail to ms. ann (sony alpha customer service )
6. write some bullsh*t how ur camera failed you. and ask how can u do ur warranty without a reciept because u got it as gift
7. they will give u instruction how to send it in for warranty
* i went to SSC in midvalley without any documentation, just the camera, and they still accept in for me
