GIMP is the way to go. It has a bit of a learning curve but there are plenty of tutorials on youtube. You could use windows paint but even though it's easy to use it's a lot more work for less than perfect results.
With GIMP: Start with something large and figure out what part of it you want on the screen. Create a blank image of 720x1280. Open your desired image. You may wish to scale it down if it's really big.
Select the pic and do a copy. Go to the blank window and paste it in. It will overlay the blank and only 720x1280 of it will be visible. Move the image around to get the exact cropping you wish, then anchor the layer and save it as a jpeg.
Put it on the phone and enjoy
