I am about to get one of these phones(iphone 3gs or HTC HD2) but will like to have an opinion from anyone who knows a fair deal about them and must have preferably used or owned them to know the difference.I know about iTunes,but is windows marketplace any good?

I've just my iphone 3gs on orange,and i think it's miles better then any other phone. The one main downside is the battery life is rubbish, if your browsing or doing anything other then using to call people then you'll be charging it constantly.

You'll be on it on for ages checking out all the different Apps from the app store. It also has a built in GPS which is handy if your driving, no need for a satnav!.
