Yeap.. Same phone.. will never change other phone for now.. loved this phone.. its as my working tablet as well also when going oversea's for business trip..
1 year standard.. SenQ doing extended warranty but have to refer to SenQ..

Can register the warranty online if you bought a local Malaysia set. 

i only use 1 phone.. business not that big till need carry 2 phones.. haha..

Dual-core or not i dun really care coz when you use it you can tell the differences actually.. My brother got an incredible s + motorola atrix.. both performs same unless you benchmark them.. if you dont multitask much then no differences.. say lag sure got lags but if the phone didnt shuts down or restart randomly im ok with it already..
