With fear and trembling… the iPhone update & hack
Sunday, February 17th, 2008
Roughly following the vendor-linked instructions here…
- Backup via iTunes
- Download various ipsw firmware fils from here.
- Looks like I need to ‘revirginize’, or undo the unlock that I did before. Hmm.
- Tool here from ipone dev elite, their FAQ re-virginize link is borked.
- Looks like the latest iNdependance can do some of this too… Let’s try that first, it’s the simplest. Trying the ‘prepare for upgrade’ option…
- Using iTunes, ‘check for upgrade’, upgrade to 1.1.3, seems to work.
- Using iNdependance, activate and jailbreak - OK, done.
- Install trick SIM chip, using scissors to cut SIM card and tape to attach it. No work, no network shown, no error message. Hmm.
- Try installing SSH/SCP/SFTP using iNdependance. Nope.
- Try iNdependance’s SIM(software) unlock in desparation… Unlock succeeded, but with the ‘next sim’ in place the phone shows no network.
- Re-flash 1.1.3 using iTunes, try with and without SIM present, before and after restoring data…nope.
- Remove next sim, try old SIM card… same thing. Symptoms: IMEI 00 499901 064000 0, no signal on cell meter.
Time to RTFM, and according to this TurboSim doesn’t work with 1.1.3. Which means that my $20 ‘next sim’ probably doesn’t either. Damnation. The instructions claim 1.1.3 works, but a re-read of the poorly written paragraph seems to imply only that ‘works’ means ‘downgrade to 1.1.1 and unlock’ that works:

Stick sim and next sim together and put back in sim tray and into iphone. Now your ready to use your unlocked iphone!
Hmm. From reading this page, maybe I should try iJailbreak instead. It WORKS!

What’s more, it installs the AppTapp installer for you; nice touch.
OK, verdict is this:
- Use iNdependance to ‘prepare for upgrade’, not sure if this is necessary
- Use iTunes to sync for a backup.
- Use iTunes to update to 1.1.3
- Use iJailbreak to activate and unlock.
- There is no step five.
That’s it! And, what’s more, the GPS-lite WORKS!
It took all damn day, but I’m a delighted nerd. Off to donate to iJailbreak!
(And yes, the 20 bucks for the ‘next sim’ hardware was a waste. Save your money.)
One of the recurring gotchas with an unlocked iPhone is that the newer features re-lock the phone every time. Because of that, I’ve kept mine at version 1.0.2, which works pretty well but lacks some newer niceties. The
