[1.1.3 (1.1.2OTB)] Can I safely upgrade to 1.1.4?
Please correct me if I am wrong.
I have unlocked my sim using an old - not Ziphone method and updated to 1.1.2.
After Ziphone released I decided to restore to 1.1.3 (by downloading the file from iphoneunlock.no) and then I used Ziphone. I am still with 04.02.13-G9 (not sure about bootloader)
Why when I have updated my frineds phone (1.1.1OTB) he has now newer modem firmware than me?
And the most important: What should I do to have newer modem firmware and what should i do to have 1.1.4 now? I don't understand why some people use Ziphone and then have problems with bootloader? How can I safely do it?
My Iphone is from the end of December.
If you restore your phone to 1.1.4 firmware and unlock with ziphone 2.4 or above
your bootloader will be downgraded and you will have an unlocked phone with
newest baseband(modem firmware), newest firmware but older bootloader 3.9.
Restore your iphone to 1.1.4, only jailbreak and activate with ziphone 2.5c and
only UNLOCK with ziphone 2.3 or older... By doing that you can stick with 04.02.03
baseband firmware, 4.6 bootloader and latest overall iphone firmware 1.1.4...
Besides Every damn thing works like a charm...
How do you know which bootloader I have now?
Sorry I am still confused here. You suggest me using two Ziphone versions?
(I have to do something because smses open very slow I think there is some incompatibility here.
I guess newer Ziphone 2.4 or above downgrades my bootloader to 3.9?
What if I UNLOCK also with 2.5c what is wrong with it?
Which method is safer for me? Just restore to 1.1.4 and use latest Ziphone to jailbreak activate and unlock? How will I end? Is it safe?

Add www.trejan.com/irepo as a source in installer.
Install BBinfo from all packages.
Run the app and it will tell you what BL you have.
Let us know what it is and we go from there.
First ever Apple product I bought : iPhone.
He should more than likely have 4.9 since its 1.1.2 OTB but it is best to check
Thanks for you assistance, don't want to do anything stupid
Modem Firmware 04.02.13_G
EEprom version 208
Bootloader version 4.6_M3S2
So what are your susggestions?

Sync your contacts via iTunes, sou you can restore it back after unlocking is done (note: if you want to keep backups of yours sms,calldata,wallpapers,iBooks .... try using 3rd party software like iPhonePCSuite and use backup function and after unlock use restore)

.... Now, you should choose to keep your Bootloader or to DOWNGRADE to 3.9.....
Note: Currently there are serveral very intense threads around here about this .... but main issue is this if you DOWNGRADE you will VOID YOUR APPLE WARRANTY, and,at least for now, there is no (easy) way back to 4.6
So if you made your decision, and decided to DOWNGRADE your BOOTLOADER follow this guide :
If you want to KEEP you bootloader, my advice to you is to download ZiPhone 2.5c from www.ziphoneorg.com/, it have UNCHEKED BY DEFAULT DOWGRADE BOOTLOADER option .... GUI is very clear and understandable and you should have no problems .... and will end up with unlocked 1.1.4 iPhone in a few minutes
Or follow this guide: http://www.hackint0sh.org/forum/showthread.php?t=32625
Now, about backup:
This is the quote from READ.ME which comes with ziphone :
If you find any missing icons or the iPhone is "strange" may be due to old settings files being
restored to the phone after iTunes finishes installing firmware. Be sure you choose the option
to NOT save settings and to treat the iPhone as a NEW PHONE. This is especially important if
any other jailbreak solution was used on your 1.1.3 phone before Ziphone.
So, you will need to set up your unlocked 1.1.4 as a NEW iPhone in iTunes, then you can retrive your contacts (and the rest of the stuff, if you used iPhone PCSuite)
Happy Hacking ....

Thanks a lot for a clear manual! So I have the newest baseband for now and official Itunes upgrade won't do anything harmfull?
What people usually do to brick their IPhones?
1. I bought it in US and am in Europe so warranty is not important. Is it better to downgrade the bootloader and why?
2.In wchich step I have upgraded my bootloader before? When using Ziphone I guess?
And one more: is it the same when I download 1.1.4 file to my computer instead of upgrading my IPhone on-line?

I read a tone posts about it: why should I downgrade my bootloader? Does 3.9 work better? (now f.ex I have to wait 10 seconds to open SMSes)
If I decide to downgrade may I use also the newest Ziphone and to check the option to downgrade manually?
