Hi, I am one that is taking this Jailbreak very slowly. I switched over from a blackberry to iPhone 4 back in November and REALLY LOVE the iPhone 4. I consider myself very PC knowledgeable and have been reading about the Jailbreak options for the past few months. I am satisfied with the current state of the iPhone 4 but would really love to have the option to use MiWi hotspot so my daughter can connect with her iPod or laptop while traveling on the road. After seeing the Verizon Hotspot being offered today, I am hoping it will come to us in a new release of iOS. But I am itching to try this jailbreak. I was hoping someone could help explain something for me. Once again, this is a new iPhone 4 with iOS 4.2.1. If I want to try this Tethered version of Jailbreaking, do I need the shsh blobs i keep reading about, or is it even possible since I don't have previous shsh blobs? And what exactly is shsh blobs? Thanks - Ron -<><
