Nice app... One thing I noticed about viewing images on the Storm in general (coming from the browser). It seems images are always compressed (even if you have your browser set to "High (Slower)" for Image Quality in General Properties). Once you are viewing an image, choose "Full Image" and then it will reload the image in full, and then save it.
The Lightning Storm Wallpaper under Nature is a good example. Looks pretty bad when viewed (and compressed) vs the Full Image.
Yeah the browser will distort the quality when viewing it on the browser, but when you save the image it will go back to its original quality. There is no way around this really using the blackberry browser.
I downloaded it, but i don't like the fact you just have all wallpapers mixed all together. if they were broken down into catergories then it would much better imho.. but thats what you wanted feedback hope it helps!
