I bought my IPAD 16GB 3G from a friend's friend a couple of months back. I have been thinking of updating the OS (current version is 4.2.1) and thought of checking out this forum before doing so. In the process I learned about jailbreak.
Now I am wondering if my IPAD is jail-broken. Is there any way to tell if this IPAD has been jail-broken? It has Cydia installed on it.
