Go to Cydia and make sure that you have the BigBoss repo in your source section. Then if BigBoss repo is there, return to the search bar and look for InfiniBoard, it's a paid tweak.
Then stop talking about infiniboard if you can't pay for it. And if you haven't read the forum rules I'm inviting your to read them all so that you do not mention anything about cracked apps on the forum anymore. Thanks for your understanding and you respecting the forum rules from now going on. Let's keep it all legit.
