iPhone but if you're developing an app for DHC I'd say "don't bother": surfing the web on a phone is akin to pulling your own teeth while stabbing yourself in the eys with sharp sticks. They are fun toys and nice phones but not serious internet devices.
I have to disagree, my phone performs very well for me on the net, there's been many times I've had to moderate the DHC site from my phone and had no problems any one of those times,
I've also bought a few items off of Ebay with my phone and thanks to my phone I was able to save money on several big ticket purchases. Now, thanks to my smartphone, if I'm at home depot and need to make a purchase, I can check to see if the items are less at Lowe's, I find myself shopping like that everywhere now.
