Although iPhone unlock is not demanded as much as it was a year ago, there are many people who need unlocking tools to unlock their iPhones. Unlock tool for iPhone is not demanded as much as it was before because Apple now sells officially unlocked iPhones. But if you have an AT&T (GSM) iPhone 4S it would be better (cheaper) to unlock it rather than buying it officially unlocked from Apple, that’s why we still need to unlock tools software or hardware-based. The software-based unlock ultraSn0wย has not been updated to unlock newer basebands ever since iOS 4.0 came out two years ago with the release of the iPhone 4. That left iPhone 4 users on newer baseband released after iOS 4 with no way to unlock their phone until Chinese company ApplenBerry released their hardware-based unlocking tool GEVEY SIM, which allows iPhone users to unlock the iPhone on any baseband included in iOS versions below iOS 4.3.5. ApplenBerry has notย releasedย GEVEY SIM that works on iPhone 4S or iPhone 4 on iOS 5 or newer firmware’s baseband.
However, another Chinese company by the name of ChinaSnow has created another hardware-based tool similar to GEVEY SIM thatย supposedlyย unlocks the iPhone 4S on basebandsย 1.0.11, 1.0.13,1.0.14. ChinaSnow calls the tool TPSIM and works on any iPhone 4S even without jailbreaking, just by inserting the SIM into it. TPSIM also works on iPhone 4 unlocking basebandsย 1.59.00, 2.10.04, 3.10.01, 4.10.01. TPSIM features:
- 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 isย NOTย supported for now)
