The iPhone Dev team that works very hard for Free to bring Free unlock solutions for the iPhone users, for the past few years they had been getting the best of Apple but the Times have changed. Since the release of iOS 4.1 there has been No way to Unlock the newer Basebands using the traditional Jailbreak and ultrasn0w method. That is about the change because there are third party Developer that have come to your rescue, they have developed ways where you can unlock your phone without jailbreaking i.e. no loss of warranty.
There already two methods out there Gevey Sim & CutYourSim and this new method is Called Rebel Sim All the way from UK.
What is Rebel Simcard and how can this Unlock My Phone ?
Rebel Simcard is a very thin and is made of a Flexible PCB that sits on under your network simcard. The Rebel Simcard Can allow unlocking of 1000;s of mobile phones without using cables software or codes and Best of all Without Loss of Warranty.

Rebel’s Micro Sim is a bit more affordable than Gevey Sim & CutYourSim , costing about $65in the pro variant or $48 for the lite version. What’s the difference between those two? The former ships with a custom iPhone 4 SIM tray that keeps the electronics inside the handset while the latter option does not require a special SIM tray for your iPhone 4 and the components are located on the outside of the handset, which isn’t aesthetically pleasing (see below). Both solutions unlock iPhone 4s with basebands 1.59.00, 02.10.04, 03:10.01 and 04.10.01 and support iOS 4, 4.1, 4.2, 4.2.1, 4.3 and 4.3. Like CutYourSim, it’s an untethered solution which doesn’t require a jailbroken device so it should appeal to casual unlockers. Unlike the former, Rebel’s use of a custom SIM tray lets you update the SIM Software even if Apple redesigns the iPhone.
The Rebel Sim is Available here for purchase in India, UK, USA, Canada and few other countries.
