I know this has been asked and answered plenty of times already. My understanding is that iPhone warranty is honored only to the Country you bought it from. My personal experience also is that local authorized service centers ask for proof of purchase when claiming for warranty. What confuses me sometimes is that resellers, of unit bought elsewhere (not from local authorized resellers), claim that one can still claim warranty locally even without the receipt. Has this changed? Can one really claim warranty without proof of purchase for those bough locally? Can one really claim warranty by just using the serial number for those not bought from a local authorized reseller?
