TPSIM: Unlock iPhone 4S baseband 1.0.14, 1.0.13, 1.0.11 without Jailbreak

A big reason to jailbreak iPhone 4S is to unlock the device and allowing it to work with carriers other than AT&T (like T-Mobile in the U.S.). But unfortunately, the hackers haven’t been able to break the iPhone 4S baseband firmware completely. Though they have achieved some sort of luck on unlocking baseband 1.0.11 and 1.0.13, the iPhone Dev Team could take some time before it is ready for public release. Even GEVEY Ultra doesn’t support unlocking iPhone 4S modem firmware baseband 1.0.11 on iOS 5.0 and 1.0.13 on iOS 5.0.1.


Another SIM interposer – ‘TPSIM’ has just been launched which readily unlocks your
iPhone 4S running on baseband 1.0.11, 1.0.13 and 1.0.14. It even supports unlocking its predecessor iOS device iPhone 4 on baseband 1.59.00, 2.10.04, 3.10.01, 4.10.01. The interposer in question is a piece of hardware which sits between a SIM card and an iPhone’s baseband. By buying this little add-on, a user should still be able to unlock an iPhone 4 or iPhone 4S on iOS 4.0, iOS 5.0, iOS 5.0.1. Supports 3G, EDGE, MMS, Facetime too.

This custom SIM-tray/card combo for iPhone 4S/iPhone4 also works without jailbreaking and keeps your warranty intact. It sells for $85. The actual retail price is US$99.95 but they are providing 15% discount for a limited time. If you’re still keen on unlocking but don’t want to pay such exorbitant rates, there’s no other option left for you except to wait for free ultrasn0w unlock. Following is the list of iOS firmware. With TPSIM there is no need to dial 112 (after the first time initialization) and the team behind it claims to unlock ALL worldwide networks.
