Read my horror story with iNdependence on a 1.1.4 updated 16GB iPhone. Don’t use it and don’t upgrade to 1.1.4 yet. 
iNdependence released an Activation / Sim Unlock solution for iPhone 1.1.4 firmware! That was fast, though 1.1.4 got not-so-interesting updates ( a probable SDK support maybe ). This version uses gunlock sim unlocking solution from Geohot 🙂 They claim this tool to be a much more efficient solution compared to Zibri’s offerings.

Download iNDependence v1.4b5 for your Macs!
– iTunes 7.6.1 Support
– Added SIM unlocking on firmware 1.1.4 (using gunlock)
– Changed …

Apple released firmware 1.1.4 with no major upgrades which means it is intended to support the forthcoming SDK. For all those waiting to buy an iPhone might want to buy an iPhone right away cos’ we can still get iPhone 1.1.3 OTB and once 1.1.4 OTB iPhones start shipping, that may pose problems.
Don’t Upgrade to 1.1.4 if you need an interruption free iPhone Usage (Apps and Stuff!)!!

Zibri’s Jailbreak works just fine but itcannot be Activated, so non-ATT users might want to wait a while before updating. All in all, another …

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 …

This is by far the best, most efficient unlock EVER! Buy a phone from an Apple store, download iJailbreak on any Mac in the Apple store and unlock it then and there!! It can never get better and easier! I tried this unlock on different bootloaders and basebands ( 4.6 BL. 3.9 BL, 04_01_13G, 04_02_13G and 04_03_13G basebands).

The best thing being – it brought a no-wifi, no-radio DEAD bricked iPhone to back in life in about 2.5 minutes!! I spent 10 hours on the dead iPhone with no success until …

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 …

It was a tension filled day since I had to make some decisions like buying a 16GB iPhone since I already bought an 8GB version 10 days ago. I was secured with a return policy but paying a restocking fee ($40) really upset me. I am spending over my budget on Apple!! My 10 day 8GB (1.1.2 OTB) iPhone was Activated, Jailbroken and Cingular activated (no contract) with 1.1.3 glory and I saw the 16GB iPhone via Digg.com I was restless, I had to get this memory-upped version before my …

Interestingly, the 16 GB iPhone rumor came true all of a sudden without Apple creating much hype this time around. Too bad for someone who bought an iPhone last week cos’ $100 is not bad for an extra 8GB flash memory. Well, since the iPhone is covered with a return policy (14 days – 10 % restocking fee : $40 ) I may well go for the upgrade once the bootloader and firmware version on 16 GB OTB iPhones. I am pretty sure it is 1.1.3 OTB but am waiting …

Today both Zibri and Geohotz have released different unlock methods for 1.1.3. Zibri’s release can unlock an iphone with 1.1.3 and 04.03.13g. It is only for BL 3.9 and don’t forget to set autolock to never and airplane mode before running it from springboard. It is available at http://rapidshare.com/files/89226222/anySIM1.3.rar.html
Screenshot-
The Geohotz unlock uses the same method as ipsf to unlock the phone but the problem is that everytime you restart the phone or swap sims you need to run signal.app to get the signal. More info about it at http://iphonejtag.blogspot.com/
