UPDATE #6: Another competitor came in to scene with a different product name. It should operate the same way.
UPDATE #5: TPSIM is the official product name for this new unlock. See alternative information from MayPalo with video proof. We wanted to upload the video to YouTube but the connection is horrible from here.
UPDATE #4: Pre-orders now available!
UPDATE #3: It also works on iPhone 4 baseband 1.59.00, 2.10.04, 3.10.01 and 4.10.01. Unfortunately 4.11.08 is NOT supported.
UPDATE #2: Screenshot of the video proof below with some explanation on MEID.
UPDATE #1: I’ve personally seen the video, an iPhone 4S locked to Japan’s Softbank is unlocked with this SIM interposer! Will try to share.
Apparently the new iPhone 4S basebands 1.0.11 (iOS 5.0), 1.0.13 and 1.0.14 (iOS 5.0.1) are exploitable, which is similar to earlier iPhone 4 basebands that can be unlocked using Gevey Turbo SIM. It will also use a SIM interposer.
This time, the new unlock won’t be from Gevey or applenberry, but rather from an unknown Chinese company.
Based on the screenshot from the video above, this is confirmed to be an iPhone 4S as it shows the MEID. An MEID is a unique identifier found on CDMA handsets within the United States (and countries like Japan). The MEID system is compatible with the existing IMEI number system used in GSM and UMTS handsets. It is being phased in to replace the ESN numbers currently used on CDMA devices, since the pool of ESN numbers has been virtually exhausted due to the number of devices in use.
MuscleNerd and Sherif_Hashim, the two prominent iPhone baseband hackers who have successfully unlocked iPhones in the past, admitted that newer iPhones are becoming harder to unlock. Thus SIM interposer is the only possible solution for now. Even sherif_hashim used Gevey Turbo SIM on his iPhone 4 before (he’s now using a factory unlocked 4S). Software unlock like ultrasn0w could be a thing of a past, unless a real genius like Geohot can develop it.
According to my trustful source, the factory plans to produce about 20,000 pieces in the first batch, subject to demand.
Some of the features and specs:
- F981 chip for high performance and low power consumption
- Custom SIM tray made of steel
- One time dialing of 112 (required for first time use)
- Facetime, EDGE, 3G etc are all supported
- No jailbreaking required
- Supports iPhone 4 baseband 1.59.00, 2.10.04. 3.10.01 and 4.10.01 (4.11.08 is NOT supported for now)
Unfortunately for those who are still waiting for the unlock for iPhone 4 baseband 4.11.08, there are still no news as at February 10, 2012.
We will update our online store in the next few days to start accepting Pre-order is now available. We won’t be doing this unless we’re pretty convinced that the unlock for iPhone 4S is really coming.
Watch this space as we’ll reveal the details as the date draws nearer.
