As I type this, my iPhone is getting all it's iTunes content back
*sight*
Here's my experience:
I had a 1.1.1 OOTB iPhone which I unlocked with anySIM 1.1. Everything was fine and dandy and I didn't had any reason to update to 1.1.2
1.1.3 Jailbreak news came. I jumped on the Soft-Upgrading bandwagon.
I decided to go with the Official Dev Team method... but the whole "You need to be on 1.1.2 in order to use this method" made me think twice. I was aware that, in order to have an unlocked 1.1.2, I had to use an unofficial version of anySIM and risk my iPhone. I thought about it for a while and said "Fuck it, everything's going to be fine".I did the whole 1.1.2 update dealio -including a painfully boring downgrade to 1.0.2 > update to 1.1.1> prepare the phone > upgrade to 1.1.2-. When my phone was ready to run the unofficial anySIM, I was really nervous... but in the end I ran the app.
Everything was ok. I had signal. I made a test in-&-out call. I sent and received and SMS. The hard part was over. Now I proceeded to to the also-boring-as-hell soft upgrade to 1.1.3. At first glance, everything was fine...
But reality betrayed me...
*Installer.app was broken. Couldn't install or uninstall shit. -and I was running the latest version of the app-.
*Contact and Calendar sync was also broken.
I didn't care much at the beginning, I was aware that there were problems but they all could be fixed by fiddling around the phone filesystem... but then, the main offender:
Fucking SSH was broken.
Basically, I was stuck with a flawed update and the only way out if there was to do another painfully boring downgrade to 1.1.1> prepare the phone > upgrade to 1.1.2 > upgrade to 1.1.3. I devoured a bunch of tutorials and read a lot of threads regarding the problems that users had with both versions of the jailbreak. Then I learned that my favorite app, the app that made my iPhone my most beloved gadget, MobileScrobbler, doesn't work on 1.1.3
I bailed out of the Soft-Upgrading bandwagon, and jumped on the Downgrading to 1.1.2 one.
Now, after 1 hour and a half, I have an unlocked 1.1.2 iPhone with all my apps working flawlessly. Alas, during this whole process I learned that 1.1.2 is way better than 1.1.1, mainly because of the improved battery life, "snappier" behavior of the OS, improved stability, improved speaker's volume, and the ability to export custom ringtones from GarageBand straight to iTunes with no workarounds involved.
Conclusion: If you have a jailbroken phone, don't update yet to 1.1.3. Make yourself a favor and try 1.1.2 meanwhile if you haven't. When everything gets sorted out, and when apps start working on 1.1.3, then will see.
iTunes sync is done. Talk about timing...
