Can a NEW iPhone with iOS 4.2.1 be teethered Jailbroken?
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 -<><

You can use Redsnow to tethered JB 4.2.1. Note, with a tethered JB, you must use Redsnow everytime to be able to bootup the phone.
As for SHSH, they are security checks to allow or deny you the ability to restore with a firmware. Since Apple only allows you to install the current version (4.2.1), you must have saved old SHSH files to trick iTunes into allowing you to restore with older firmwares. SHSH files are unique to each iPhone and firmware version. And, what SHSH files you can save has nothing to do with what firmware your phone is currently running, you what's Apple is signing / sending out.

I downloaded TinyUmbrella, saved my SHSH files.
Downloaded redsn0w 0.9.6rc8 and a copy of 4.2.1 IPSW
I successfully Jailbroke my iPhone, installed Cydia, MiWi and other programs and got them to work successfully.
I noticed my bluetooth does not work and have been reading that this is a known isssue. I then saw a 0.9.7b5 release of redsn0w that seems to have the bluetooth bug fixed. Is this the latest release? My question is:
If I want to use a new version of redsn0w, do I just run the new version and choose the option to "Just boot teethered" or do I have to choose some other option?
Ok after reading more on this, I think this is a Beta version released only for Mac's and beta testers, but I would still like to know when I run a newer version of redsn0w, will I have to do anything special, or just run it and choose boot teethered?

Thanks, yall have really helped me understand a lot. I re-synced my iPhone and backed it up this morning. So if a new redsn0w comes available, I should:
1: connect to iTunes
2: Click on Restore under the Version menu
3: Right click my iPhone in the side bar and choose Restore from backup.
4: Then run the new redsn0w
is this Correct?
