i also have question on warranty...

i have this Certificate of warranty in my box that says 'mail this portion back to samsung malaysia electronics (sme) sdn. bhd. with small boxes to fill up details.. do i need to mail it back to them to get warranty? (bought this from maxis)

also i got this e-warranty user information paper.. is says to check warranty period, send PC<space>IMEI NUMBER but it never specify the sms number to send also... what's the number?

Thanks!
