its a 3d hologram sticker with 'PlatinumWaves' wordings on it sticked on the left tophand corner of the tab.. but the box does hav the e-warranty sticker on it, so ur saying the ap sets dont? maybe platinum waves is the authorised distributor of SME in east malaysia? i dont know..even tried googling it but not much info on it.. other samsung model also having the same sticker, but not all of them though..i really think that those are ap sets..
If i hav the time i will take a pic and post it in here..
