I followed these instructions carefully and I was in a neverending reboot. I ssh'd back in and erased what I did. I've been able to use my iphone, but have somehow sms messaging no longer works. When I click on messaging the screen where there should be a list of my old messages shows up blank and launches a new message for me to send then it closes. I have not been able to get or send my sms messages since. Please someone have a fix to this or tell me which command to use to get my sms messaging back to normal. I've restored like 5 times, I tried ultrasn0w and blacksn0w to unlock. I even downgraded back to 3.1 without any luck. iphone 3g 8gb jb: pwnage ul:blacksn0w Thanks in advance!

iphone crash after following these tutorials to enable tethering!! I am in big trouble with my iphone 3GS, jailbroken with Blackra1n, firmware 3.1.2 and baseband 05.11.07. I am using the last itunes (9.0.2) My goal was to to enable tethering on my iphone. I first installed openSSH by following this tutorial: https://iclarified.com/5637. Then I installed Fugu with this tutorial : https://iclarified.com/2096. At this time I reboot the iphone and everything was fine. Then I finally followed this tutorial to enable tethering : https://iclarified.com/5634 I think I did not reboot at this time. To install my carrier settings I used this website: bluebanana.fr I installed this carrier settings « Bouygues Telecom France v6.3 ». After all this I restarted my iphone and it never restart again ! It always freeze on the apple logo and restart as itself. Its a neverending reboot loop. I try the recovering and hard recovering with itunes. Itunes can see the iphone but when it start the recover it freeze with an empty status bar on the iphone. Then itunes stop and show « waiting for iphone error 9 ». What can I do to save my iphone ! Please help

Since the is no Fugu fo Windows users, use NetDragon iPhone PC Suite to do file transfer, permission change and renaming of files. For patching and SHA1 compare, I used Terminal application on OS X.

Too cool - all works fine (posting this using tethering now). Thanks for another easy to follow and handy tutorial!

This is too much work. I just install RockID app, then open RockID to download 3G tethering. Then, go setting--> general--> network. Tethering ready

Works perfectly. The instructions aren't the clearest and I'm no expert but this has just worked fine on 3gs 3.1.2 This tutorial made the internet tethering option return in the network settings page, I then reinstalled the 02 profile that I had previously been using and turning it on. I did try using PDAnet from Cydia but its not great, the connection was dropping out and the speeds were not what I would get from standard tethering. Thank you to whoever found/created the tutorial.

Did it. does not change anything. I mean everything looks okay and the phone still works etc, but no tethering.

Does allthis mean that you willonly be tethered by wi-fi using the networkIP address installed and if one wanted to tether away fromthe networkone would have to find a wi-fi network and get its IP address and reload

I did all of the above, and the installed the profile at Benm.at. The tethering works, but then it stops my visual voice mail from working.... Anyway to get both of them working at the same time?

I finally got the commcenter hack installed, and did all the other steps in this tutorial. Total Waste of Time! the musclenerd Tethering does not work on a PowerPC Mac. PDANet does work, and I recommend it. Very easy, MUCH easier than this tutorial for the musclenerd hack, and MUCH easier than enabling the tethering toggle with BenM's files, which do NOT actually enable tethering at all.. I dont know why people dont just use PDANet. It was free too.

Has anyone heard if dev team is working on a 5.11.07 unlock? I have two paper weights sittin here so I was just wondering if there was any new news?
Mark
Mark - October 20, 2009 at 3:10pm
two?? you'd think people would learn their lesson after the first time, to not update their itunes or iphones without the greenlight from dev team!! =p
Josh
Josh - October 20, 2009 at 4:35pm
They are just two I recently bought to jailbreak, unlock and resell that had already been updated. I have two others that I use that are unlocked....... So yeah I am smart enough....
