The FatWatch 1.1 update is now available for download on iTunes, just after the nick of time. While I was able to update my own phone without any problems, I’ve heard that others have seen their data disappear when they update other iPhone apps. To guard against this, I posted some instructions on the website on how to safely upgrade, by using Wi-Fi Import/Export to make a backup first.
I’ve been trying to update the screenshots on the iTunes Store, but the upload page just fails and tells me to try again later. So that’s what I’m going to do. Until then you’ll have to live with 1.0 screenshots in the iTunes Store.
