like AJ said, upgrade yours to 4.2.1 through iTunes, then go to www.iclarified.com for step by step tutorial on how to jail break your phone.Yes it works. I just want the most recent update for my 3G. But I have no jailbreak experience.
I'm getting annoyed that I can't download or start up almost any new app.
Haha and imagine they're asking 45 (about $60) here in a shop for an update, that probably isn't the best one and loosing all your files...
Yeah that's true.It not worth it to pay them anything to do this. By doing this, you are learning new skills as well. You can't brick an iPhone by software. So, try it and come back here for guidance if you are facing any issue.
You have restore your phone to the latest 4.2.1 firmware. So, the next thing to do is to go to www.iclarified.com to get tutorial to jailbreak/hactivate your phone so it by pass the activation/emergency screen.Okay, so far I've let iTunes update my iPhone. But I don't know if it's updated yet. I only read restore and things like that.
Now it is in the mode that it hasn't got the right sim card in it (cable+itunes logo+emergency call). The iTunes button is now like the new one. Does that mean my phone has got iOs 4.2.1 now ?
Should I start jailbreaking now then or do something else?
Glad it works out for you. I can't take credit here. It is a team effort and everyone is patience to work through problem and learning from it. Enjoy your phone.I've tried the c16 version. But then it always shut down when it was fetching the iPad baseband.
So I searched a little on the net and someone with the same problem, had solved it when he used the 0.9.6b5 version. So I tried the same.
From on then, everything went fluently! Now my phone is jailbroken & unlocked and has 4.2.1 software! I'm very happy!
So I want to thank everyone and especially Crystal-RX for always helping me out when there were problems. Big thanks!
