Surprisingly good panoramic with Iphone 4 and apps

I normally use a dSLR and/ or an Olympus OM-D E-m5, but I have been experimenting a bit with my "old" Iphone 4 lately. Here's a recent shot using the Camera+ app to take 2 shots side by side, then the Auto-Stitch app to create the panorama, then the Snapseed app to sharpen and tweak it a bit, then e-mailed to myself to store on my computer. I was quite impressed with the quality.
