One of the best things about using Snapchat on iOS device is that it has geo-filter feature. It adds a special overlay for Snaps that were taken at certain locations or at a special event. The fun doesn't stop there if your iPhone or iPad is jailbroken and installed with Phantom Jailbreak tweak for Snapchat.
This is a Cydia app that allows you to use certain additional features that Snapchat app itself doesn't have. And removes anything that may cause annoyance while you're Snapchatting with someone. These features include taking screenshots without the other person knowing, keep the snap playing for unlimited time unless you choose to close it, send images or videos from your Photos app, and most recently, fake your Snapchat location.
I have been searching for a way to do this just to mess around with my friends on Snapchat but I couldn't find a solution until a recent update of Phantom for Snapchat. Cokepokes just pushed out an update for his popular tweak that now let you change your Snapchat location to Paris or Hawaii even when you're not even in those locations. In other words, you can take a quick little selfie in your room and have the geofilter say that you're in Dubai.
Of course, you will need to jailbreak your iOS device first before getting this awesome feature for Snapchat. Once your device is jailbroken, go to Cydia and add this repo: http://cydia.cokepokes.com. Now find and install Phantom for Snapchat tweak.
Launch Snapchat app and take a picture, you will see a new button being added to the bottom of your screen along with the timer, T icon (Text) and a new spoof location icon. Simply tap for a map and hold on to your desired location. As usual, the geofilter won't be available right away, you will have to swipe right or left on the screen to go through several filters until you find the geofilter for that specific location.
