I picked up the HTC Hero for my Sprint account yesterday. So far, I love it. Of course, my last phone was the free one I got five years ago and hasn’t worked for a couple of weeks, so just about anything would have been an upgrade. You can read real a real review of the ins and outs at Gizmodo.
Me, I’ve installed Pandora and a compass app. Once I get my Exchange account to sync I will be complete. I do like the fact that you can run multiple apps at once and can expand the memory with a standard card. Other phones *cough*iPhone*cough* don’t do that.
