The news are flying fast. HTC HD2 is “heard” to be selling at SG$348 if you pre-order from HTC during the Sitex 2009 (a discount of SG150) with a PowerValue 300 plan (SG$48.15). This information is taken via Twitter (OCWorkbench) and I source around and found it from lukeforceone.
I digged the news and it reaches Mobinauts (previously known as PPCSG) and they were discussing about the pricing as Starhub started to contact those on the list.
So, I extracted their information.
Original (SG$598) – (SG$150 from Sitex 2009) and with Starhub PV300 = SG$348
Original (SG$598) – (SG150 from Sitex 2009) and with Starhub PV100 = SG$448
Do not quote me. But if this is true, HTC HD2 is sold at a very cheap price and with trade-in, the deal is even sweeter!
Finger Crossed for Starhub to contact me!
