Hi, I am new to the iPad. Reading this forum I had been learning a lot, but also new doubts appeared. For now, my main conflict is to JB or not. I know that this question is not only mine, so I want you to help me to collect information in one thread for reference to the beginners in the iPad world who are facing this decision. What is Jail Break? How do I JB my Ipad? Why the version is important? What is Cidya and how it works What happen to my apps bought from the store? Is it possible to reverse the process? How? Tethered or untethered? Which is the difference? My main purpose in JB is to use sd cards for extra memory, is it possible with 4.2.1? Does it really work? Ifiles from app store works with a JB iPad? Main Advantages Main Disadvantages Known problems Thanks to all!!
