Hi there! I've found a way you can hack Snapchat on iPhone without jailbreak.
It looks like you can download an add-on kind of app for Snapchat called Phantom, which allows you to write as much text on your snaps as you want, change the fonts to fancy ones, change the colour of your text and save all of your snaps without having to screenshot. There are three simple steps:
1. Add the source apt.modmyi.com
2. Go to search and type in 'Phantom'
3. Download Phantom, then follow the instructions!
Remember, this probably isn't allowed in Snapchat's terms and conditions, so you might find that one day Phantom stops working, or, worst-case scenario, your Snapchat account gets disabled.
