Tough call.....I have had iphone 3GS 32GB, HTC desire HD and have now moved to iphone 4. And heres why....
iphone 3GS....great simple, fast and does what it says, build quality good, but looks a lil dated now. Technol' moved on. Great Apps.....via the store.
HTC HD....liked the phone, BIG tho.....great screen for web, email, and movies. Too big for my pocket.
I had issues with syncing photos, movies and music on via a 32 GB card. Compared to the iphone.....it was getting a lil messy; I spent a weekend sorting....compared to 30 mins with an iphone.
Technically a great phone, I like the customisation options with desktops and widgets....but these all drain power if syncing with the web. constantly.

iphone 4....as it says on the tin! screen is great, simple apple options, front facing camera....I like the whole easy sync process with itunes....which how my library exists.

The samsung galaxy S, for me looks like a iphone 3GS, technically good but but feels plastic....no feel good factor here!

Hope this helps...my take only!

Only a standard HTC Desire here but i'd not be without it.

Pros: Screen quality & the applications that are coming now.
Cons: Battery life, pocket dialling

From what I've seen, the HTC phones are very good. I will be in the same position on Feb, but I'm opting for an Iphone 4.

HTC Desire is probably the best phone on the market right now.

rlHTC vs iPhonerl

Lol. There is hardly anything between them except the iphone is ridiculously expensive.

Which is exactly why i refuse to have an iPhone. That and no flash!

I know, which is why that's one of my favourite vids. Sums up the attitude of many iPhone buyers perfectly.

Have to say the new Blackberry Torch is an excellent bit of kit too. Have had a variety of blackberry phones and an i phone 3gs and an i phone 4 (awful - but then I got one when they first came out) and the Torch is superb!

Main reason why I opted for the HTC Wildfire instead of the iphone, I could get exactly the same contract on either phone but I didn't wanna pay £120 for the iphone when I could get the Wildfire for free. The only downside to this than the iphone is the apps, the andriod market is rubbish and hardly any decent apps unless you're american then there's loads of good ones I'd guess other than that there's nothing between them, really.

I'm due a new phone in a few months and was considering the Torch but Blackberries seem to get a lot of poor reports so I am more likely to go for the Desire.

The apps available for iphone are very good.

Blackberrys are good phones, I just really don't like how they look at all.

The Torch is on a different level to other blackberry's though. I had the 9700 Bold previous and upgraded to the Torch and it is massively better. Horses for courses though as I use mine for work a lot and have a multitude of e-mail addresses that all feed in. The youtube player on it is very good too and seems to be much better than the one on the i phone 4, it certainly buffers less.

Once you go black you never go back.
