*UPDATE* You can get the Jawbone UP from Apple Store (Singapore) as well but the waiting time is 8-10 weeks!
Jawbone UP finally came to Singapore! I am not too sure the exact date it goes on sale. It was announced back in late March 2013 and I saw it selling in Challenger (Funan) on 10th April 2013. I bought it on 14th April 2013 after contemplating it for 4 days.
