When upgrading to another iOS device, you can transfer the app's data by doing a proper backup and restore. This means you can transfer saved settings and unlocked collages from the "Free Layout of the Day" rewards. Please note that it is not possible to transfer app data from iOS to Android devices and vice versa.
After you select a photo the Photo Editor opens. The buttons at the bottom of the photo editor are scrollable from right to left. Scroll them until you find the Text button or the Meme button. The Text button lets you put text anywhere on the image. The Meme button lets you create a Meme on the photo, which is, half of the text message on the top of the image and the other half on the bottom.
There are actually two upgrades available. The first is called the Borders Add-On Pack and the second is the Frames Add-On Pack. The Borders Pack will give you added features to change the border color, size, texture and round the corners. These features are available from the toolbar at the top of the main collage creation page. If you have this toolbar, then you have the Borders Pack.
Under the Export menu look for the "Print to Walgreens" option. This is available only in the United States. Follow the order process to select your nearest Walgreens store and order your print. When your print is ready to be picked up you will get an email from Walgreens. Pay at the time you pick up your photo.
In order to post from Pic Stitch to Facebook you must be signed into Facebook in the iOS Settings. To do this open the Settings app (that's the grey icon that looks like a gear). Scroll down until you find Facebook. Tap that and then sign in to Facebook here. These are built in Facebook settings specifically for iOS, they are not related to Pic Stitch in any way and Pic Stitch, as well as all other apps will still have to explicitly ask you for permisson in order to access Facebook.
