Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Ah, Also its nice to know what the unlocked box contents are (source amazon.co.uk):
* HTC Hero 3G Android Sim Free mobile phone
* Quick start guide
* Screen protector
* Travel charger
* Mini-USB data cable
* Standard battery
* Wired stereo headset with 3.5 mm connector
* Accessory leaflet
* 2 GB microSD card
Hopefully the Orange package would have a bigger SD card
