I'm also really keen on the phone. However I have a few reservations, hopefully you guys can share some opinion on it.
1) Warranty issue - since this is a first gen phone, it might be prone to some major bugs/probs , without the warranty(buying frm jp) - is it still safe?
2) amazon listing - any idea when the asia version will be available? (probably offer warranty as well)
3) cost of fixing - i und even with warranty nobody in sg can help - it needs to be sent back to US/JP , how much would the repair usually cost?
Just feel that without all this support and warranty, might not be worth shipping it over

especially since its not as affordable as n4.
