Hi:I want to see what the fuss is all about. I`ve been a PC tech for awhile but this Ipad is my initiation vehicle Right off the bat,i miss the extention slots... guess you use the cloud service but i don`t know much yet. And so,what are the +`s and -`s of jailbreaking? How and why should anyone do this? Many more questions to come and thanks for this group!
