iPhone 3GS – Notes on How To Restore, Apply SMS Security Update, & Re-jailbreak

Last night I got into ‘have my cake and eat it too ‘ mode “ as in, I decided I needed to apply the 3.0.1 urgent security update for the iPhone, but also wanted to get straight back to being jailbroken.

I managed to get both things done last night, and took some quick notes along the way.  Thought I ‘d share those here, in case any of you are thinking about the same sort of process.

Here ‘s what I did after coming home from having a few beers with some work colleagues I hadn ‘t seen in way too long (all the best decisions get made after a few beers right?):

I already had a recent backup, otherwise I would have done that as Step 1 “ so I skipped straight to this process:

1) Did a DFU mode restore to get the two files that are needed in order to  ‘safeguard your jailbreak’ once OS 3.1 comes out (IBEC and iBSS) – per these instructions at the iClarified site, which are recommended by the Dev Team, for Mac and 3GS: http://www.iclarified.com/entry/index.php?enid=4400

** If you need a reminder on how to get into DFU mode, iClarified also has you covered here: http://www.iclarified.com/entry/index.php?enid=1034

2) Setup as New phone, not from backup (as is nearly always the best move in these processes in my experience).

3) Ran the update to the new 3.0.1 firmware (with the critical SMS security fix) via iTunes.

4) Downloaded redsn0w 0.8 3GS for Mac – at iPhone Download Blog’s download page: http://www.iphonedownloadblog.com/iphone-downloads/

5) Did the re-jailbreak with redsn0w – using our friend Sebastien ‘s intructions at his iPhone Download Blog site: http://www.iphonedownloadblog.com/2009/07/31/jailbreak-iphone-3-0-1-redsn0w/

*** One important thing to note is that although you will be choosing the 3.0 firmware file during the redsn0w jailbreak, if you have completed the other steps as above, you will remain on 3.0.1.

*** I had previously been jailbroken with purplera1n, but it is not yet working with the 3.0.1 update from everything I ‘ve read so far “ and I ‘ve always had very good results in the past with Dev Team jailbreak tools.

Results & a Few More Quick Notes:

The jailbreak was quick and successful. The firmware is 3.0.1 and Cydia is installed and working.

Ran a sync to get apps / photos etc. back.

Setup main settings, email accounts and main preferences again.

Re-arranged home screens / app icons “ always the most annoying portion of things!

Started on re-installing some Cydia apps – after the install of Mobilesubstrate and hitting Reload Springboard on its Complete screen, the iPhone froze up and needed a hard reboot.  All is fine following that hard reboot.

Phone, YouTube, and everything else I ‘ve tested so far is working fine.

Battery life seems about the same so far “ and performance is still great.  

Have got most of my (small handful of) Cydia apps re-installed and working fine.

Overall, I ‘m very pleased with my results.  I ‘ve got the security patch and I ‘ve got my jailbreak back.  The whole process took around 3 hours, including syncing everything back, re-doing prefs and settings, and messing with home screens arrangement.  So, while far from super-quick, it was pretty manageable, and well worthwhile as I ‘m enjoying being jailbroken.
