Gevey Ultra S will unlock your GSM iPhone 4S, no jailbreak required

iPhone 4S Unlock with Gevey Ultra S

The new Gevey Ultra S is now available for pre-order and will unlock your iPhone 4S without the need for a jailbreak. Your order will come complete with one Gevey SIM tray and an Ultra S SIM which should be plug and play and require no emergency dialing for it to work.

It's worth noting that the Ultra S is only compatible with the GSM version of the iPhone 4S which means if you've got a Verizon or Sprint model, you'll have to sit this one out. Gevey also claims that the Ultra S will operate under a 3-volt standard which allows for less battery consumption. Basically, you shouldn't lose any battery life due to the unlock. It will also be completely untethered so no worries about rebooting and losing the unlock.

While the Ultra S will unlock 2G and 3G bands on all networks, in some cases you may still be restricted to 2G access. This is common with unlocked AT&T phones on T-Mobile who only have EDGE access. The Gevey Ultra S boasts the following feature set -

  • GEVEY™ True Plug-and-Play Unlocking SIM Interposer
  • No Need to Dial International Emergency Number 112
  • Untethered Unlock with no Jailbreak Required
  • Compatible with all GSM iPhone 4S SIM Cards (Does not work on CDMA iPhone)
  • Complete Unlock with all 2G and 3G data services
  • No SIM Card Cutting or Physical Modifications
  • Works on iOS 5.0, 5.0.1
  • Works on Baseband 1.0.11, 1.013, 1.0.14
  • Guaranteed Better Reception than Previous
  • Decreased Power Consumption

It's worth noting that this unlock doesn't require you to alter or cut your SIM card, which is a plus over other unlocking methods. You can hit the link below to pre-order a Gevey Ultra S for $54.99 via applenberry. Much cheaper than paying international roaming fees on your native carrier when traveling overseas. Any of you planning to pick one up?

i understand that this is for GSM. Seperate question though. Is the actual hardware exactly the same for the USA GSM and CDMA phone? If not does anyone generally know what components are different?

Ally Kazmucha says:

The difference most likely lies with the carrier software installed. Not positive but that'd be my guess

9thwonder says:

Thanks Ally. I google it a while back and mostly came back with hundreds of articles stating simply that Verizon a cdma carrier was not getting the iphone or that Sprint was now getting it. But i couldn't find one answering if they the hardware was exactly the same.

Ethan says:

So internally the iPhone 4 on Verizon is full CDMA. iPhone 4S I THINK is the identical unit.

Exwindz says:

Sounds cool.
What mod is that to have the app icons shrunk?

Bengal313 says:

I got the 32G White Iphone 4S from sprint. From what I understand Sprint, ATT, and Verizon use the same phone but only different carrier software. Can I use the Gevey on the sprint phone to be used on T-mobile.

ALV0048 says:

I too have the 32gb iPhone 4s from sprint and have been wondering the same thing. I have been waiting for a way to use it with AT&T which theoretically should be possible. The sprint iPhone 4s has both gsm and cdma capabilities. Will the gevey ultra s do the trick?

Nick says:

So I'm assuming that this will only work for 5.0.1? If I were to upgrade in the future, would the unlock still be applicable?

kaze258 says:

will it be able to be used on baseband 4.11.08

LanceWebb says:

Any word on a new Gevey iPhone 4 (not S) sim for 5.0.1 non-jailbreak?

Alukado says:

Eachsupplier com carries the R-Sim which does exactly what the gevey ultra S do, just the price is cheaper.

alex says:

Uhh... not sure about need for this if you're on Verizon.
I personally got my Verizon iphone4s unlocked for international travel by calling Verizon's 'Global Support' line at 1-800-711-8300. See this page: This was in November 2011.
I had the iphone for less than 15 days - though had that particular Verizon account valid for about 5 months. Called up and told that I wanted to have iphone4s unlocked for international travel, so I could use a prepaid phone connection in my destination country. The rep knew exactly what I wanted and was told that the lock had been released -- all in all it took less than 5 minutes of call.
Later when I went overseas, bought a prepaid micro SIM card with talk time and data, popped it in iphone and had voice AND 3g speed data with zero trouble..

dave says:

Alex, just try clarify things for others, I have done the same thing you did but not to confuse the readers, you are speaking on An INTERNATIONAL unlock which works on ALL verizon iphone 4s when you travel. If you have verizon 4s and thinking you can do this unlock for it to work on US domestic networks suchs as tmobiel or ATT then you are out of luck. Verizon will unlock your IPHONE for international USE, still WILL BE LOCKED for domestic networs here in the U.S.A.

Alukado says:

Just order the R-Sim if you need to unlock iPhone 4S, which is in stock and ready do ship, furthermore it is cheaper than Gevey ultra S, check this Source:

Malvina Perrot says:

Would this work with a Swisscom phone, and how could I get this? :)

Alise Gulston says:

Try Preserving the BB from iOS 4.3.3 to iOS 5. Use PwnageTool in the mac or sn0wbreeze in windows. Then use Gevey sim. Most probably it will get unlocked. Their site includes BB uptp 04.10 so yours should work.
