For those who can't find it or new to using Flex 2.
1. Open Cydia and search for Flex 2, look for the cracked version not the paid version (the Server Cracker only appears in the cracked version)
2. Once installed and restarted open up Flex 2
3. Click on the Cloud icon at the bottom, you should see the Server Cracker listed at the top
4. It takes awhile to load, once loaded scroll down to the T's and look for Tinder (you should see other cracks too)
5. Install Mehdi's patch and you should see a popup saying it's installed but need to activate it
6. To activate click on the List icon at the bottom, left of the Cloud icon
7. Click on the check mark on the right hand side
8. It's now activated (I know, it seems too easy but that's how you activate it)
9. Open Tinder (if you have it already open you'll need to close it and reopen) in case you don't know, double tap your home button and Tinder should show up as a background app running, swipe up to close.
In my test the patch didn't work for me but I was out of "Likes" already. I'm going to try it out tomorrow when I have "Likes" available. Good luck and thanks for this patch!
