PDA Expert sells all original devices under SIS warranty.. basiclly all HTC devices are under SIS atm.. kinda hard to find an AP set.
and the best ROM atm for HD2 is 1.66.. actually to flash a ROM is very easy.. u just need to go to HTC's official website www.htc.com
and select SUPPORT. select your phone model and it will show you all the updates for your phone.. select latest ROM update and download it.. run it like a normal .exe file and follow its instruction.. as simple as that...
if u wanna save trouble, u can simply visit the nearest SIS service centre and they will help u to update the ROM for you.. but it might take quite some time..
hope this helps.. and errrrrrrrrrrr you are gonna love ur HD2 trust me

visit www.xda-developers.com to enhance your device..

Thanks for the reply. From what I've read from this thread, some encountered bug issue with 1.66 and some don't. Let say I wanna update manually ROM Version 1.66.707.1, I don't have to backup anything right since I'm using a new SIM card for it? I just have to proceed straight to the upgrade right?

Anyways PDA Expert doesn't help to update the HD2 ROM for free? Have to go to the HTC service centre?
Sorry for asking a lot, first time buying a windows mobile phone.
