SEP (Samsung Exclusive Partner -- or sth like that) sets will give you 2yrs warranty. all other shops selling sgs2 only gets 1 yr.

for SenQ... first year is Samsung warranty. subsequent years (depending on your warranty purchased) is by SenQ (and the insurance company they use).

warranty Q... that's something only you can answer. it very much depends on how long you think the phone will last, when you plan to change new phone, etc...

that outlet with 2yrs warranty in 1U is located in front of the escalator, right? that's the SEP in 1U.

SenQ selling for 2099 as well, if i remember correctly. but there's extra you need to pay for the extra warranty. there's a SenQ warranty thread here in LYN forum. basically, no one knows for sure if the warranty claim will be honoured... coz no one's claimed before and shared. there's even on type of warranty by SenQ that even covers theft!

btw, how much are the other shops offering sgs2? its local and not AP units, right?

If you plan to keep phone for 1-2 years get extend warranty. it is not much more expensive
as for me i do not as seldom keep phone more than a year except my hd2 n nokia e71. The sgs II will be replace by galaxy note , hopefully by oct making it only 6 months usage
