UPDATE : Download ZiPhone Latest Release for Windows. A Mac version of the same can be had here.
ZiPhone GUI is built by i.unlock.no which is based on GeoHot’s unlock script which was generalized by Zibri 🙂 ZiPhoneGUI is for Windows users while Mac users have a better application in the form of iJailbreak. Talk about hackers/developers but yeah – they are the best! iPhone Devs have been keeping mum so far but hey, this method works the best!
Unlock option works with only 1.1.2 and 1.1.3 OTB iPhones and that makes …

Update : A much faster easier solution for Mac users can be found here. Windows users may resort to ZiPhoneGUI.
I am back after spending 4 hours on the entire process (which includes some hits and misses! Which means, you no longer have to figure out the right steps/combinations!!). Now the process is trimmed down to much lesser time and the best part being : No command line hackery!
All you need is an iPhone (OTB 1.1.2/1.1.3 BL 4.6), Mac (preferable) / Windows, Firmware files (1.1.2, 1.1.3 ipsws), courage to try this …

UPDATE : No more tweaking with sec packs and command line hackery! A sit-back-relax- and-let-it-do-its-magic guide is released 🙂 It is so easy a 6th grader can do it!! Unlock iPhone 16GB /1.1.3 OTB/ 1.1.2 OTB 🙂
What took iPhone Devs months took GeoHot hours to find a true Unlock! It is not based on JerrySim baseband downgrade method but a lot more straightforward!! GeoHot hints that this can be applied to 1.1.3 OTB iPhones too, so hold your breath! Come Sunday and everyone can flash their iPhones with …

I had to buy a new iPhone OTB 1.1.2 with modem firmware 04.02_13G (week 52) to test a clean update to 1.1.3 . I have used a MacBook, OTB 1.1.2 iPhone, Cingular SIM(no iPhone contract), iTunes 7.6, iNdependence 1.3.2b and lot of enthusiasm!! I have heard about different reports and I wanted to check them out. Indeed it was one smooth upgrade to 1.1.3, thanks to Nate for his decision 😉
As stated, we need to start off with a Jailbroken 1.1.2 / 1.1.1 iPhone. OTB 1.1.1 or 1.1.2 iPhones …

Now that iPhone 1.1.3 is released to the masses, do you have to click on the update button in iTunes? No wait, almost all the features except Google Maps virtual GPS are doable with our 1.1.1 and 1.1.2 jailbroken iPhones. Please don’t be hasty upgrading to the latest in iPhone firmware offering yet. This release is for the developers (err hackers?!!) who are working on decrypting the firmware files as I write this!! Think twice before upgrading cos’ that would mean : You have almost no means to get back …

The OTB iPhones with 1.1.2 pre-installed are posing some serious issues as far as unlocking them are concerned. That won’t stop you guys from using the iPhone without a contract (Cingular / ATT). Yeah, you can Activate and Jailbreak your iPhone which makes them usable with ATT and Cingular sims without a contract. Just follow my post which involves downgrading to 1.1.1, followed by OktoPrep 1.1.2 and then Upgrading to 1.1.2 and Jailbreaking/Activating it 🙂 (All the features except for Phone can be used with other sims).
The bootloader (4.6) on …
