Here is some great news for iPhone 4S users who are desperately waiting to unlock their phone. ChinaSnow is the company that has done this job to unlock the iPhone 4S using a SIM interposer which works much like Gevey. The SIM interposer is called TPSIM.

As claimed by ChinaSnow, TPSIM unlocks:

• iPhone 4S Basebands supported – 1.0.11, 1.0.13, 1.0.14
• iPhone 4 Unlock - 1.59.00, 2.10.04, 3.10.01, 4.10.0

iPhone 4 users might be disappointed that TPSIM does not support baseband 4.11.08. TPSIM is not yet available, but can be pre-orderd from BeijingRepair and it will cost you $84.95. It will be shipped by the end of this month.

Features of TPSIM:

• 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
