I'll be getting it from US in Nov-Dec.
I'm looking doubtful towards the blackberry, considering they are not too fun, and after a while, lose their charm.
I've used the iPhone 4 here, and I must say, it's a beautiful device and quite functional too. If jailbroken, I think it is as good as any android phone, and scores higher on build quality.
Regarding the Androids, Samsung Galaxy S is feature packed and considered one of the best phones around..
I'll have a look at Desire HD, but honestly, I would stay away from HTC because Touch Pro had pathetic battery life, and I wouldn't want to get into that again. I like my phone to have battery by the end of the day, and we can confidently use it without the fear of it dying out by the end of the day, when it is most likely to be needed.

Mark, HTC is a company that makes phones - the hardware
Android is an operating system - the software which runs on the phones.
The Desire HD runs on Android, as does Droid.
