I downloaded a new app for my IPhone ... Twitterific. It's a freebie for Twitterers. User friendly and free, can't beat that.
Here's a look at Etsy, courtesy of my IPhone. Don't forget, I can still zoom in and out.
Taking screenshots with your IPhone is easy. Press your home button + sleep/awake button at the same time. You'll hear a camera click. It's now saved in your photos file. It's saved as a PNG file. I upload it in Photoshop and save for the web.
