Compress photos with iPhone OS 4
One of the subtle feature improvements of iOS 4 that I find myself using really often is the new ability to compress photos sent from the iPhone.
iOS 4 gives you four compression size options: Small, Medium, Large, and Actual Size. Not only is this feature nice to make quicker work of sending pictures, but it’s also a great way to reduce iPhone data usage which matters a lot more on the new tiered data plans.
To access this feature, all you need to do is take a picture as usual with an iOS 4 device, and then go to mail the picture to someone. You’ll then get a pop up screen that lets you choose compression options.
Right now this feature is only on the iPhone but I would bet that when iPad gets iOS 4 this fall (maybe with a refresh?) and the iPod touch is updated, they will have this option too.
