Over the last day or so the unlocking aspect of the jailbreak community has seem to hit a red hot patch, with potential unlockers first all being introduced to a new method of iPhone unlocking using a procedure which takes advantage of Sam Bingner’s Subscriber Artificial Module (SAM), and now we have the news that the latest GEVEY Ultra 5.1 now supports the GSM iPhone 4 running iOS 5.1 with modem firmwares up to 04.12.01.

The update to the GEVEY Ultra SIM will come as welcome news for the many thousands of users who rely on a hardware based unlock for their iPhone 4 and the fact that the GEVEY SIM has been updated with some additional enhancements only adds to the good news. As is always the case with this type of unlock, a jailbreak is a pre-requisite, as is making sure that the iPhone has been officially activated through the iTunes software before the GEVEY Ultra is used.

The updated GEVEY Ultra, which is available as a pre-order item from the Apple N Berry website, comes with support for the GSM iPhone 4 running on iOS versions 4.1 up to the very latest iOS 5.1, and will provide a hardware based unlock for the following basebands:

  • 01.59
  • 02.10
  • 03.10.10
  • 04.10.10
  • 04.11.08
  • 04.12.01

The new product is a newly designed chipset that doesn’t require any cutting to fit perfectly in the iPhone 4 and offers longer device battery life thanks to design changes meaning that it operates under the 3-volt standard. The manufacturers are also touting improved reception, better signal strength, consistent voice calls and a better all round data connection as upgrades to the Ultra 5.1. The availability of the GEVEY Ultra 5.1 comes hot on the heels of the revelations surrounding an unlock method found by a Chinese iOS researcher that uses the SAM package from Cydia and allows any jailbroken iPhone on any firmware to be unlocked and therefore could suffer in popularity because of this.
