Most bypass tools and methods rely on manipulating the device's connection to Apple's servers. The iPhone 4s on 9.3.6 sits in a unique position:
Specifically, iOS 9.3.6 was a tether update. This means that unlike later iPhones, the 4s still uses a ramdisk-based activation system, making it vulnerable to DNS or hosts file redirects and activation record swapping.
| Feature | Status After Bypass (iOS 9.3.6) | | :--- | :--- | | Cellular calls / 3G data | ❌ Permanently broken | | iMessage / FaceTime | ❌ Won't activate | | App Store (free apps) | ⚠️ Sometimes works via legacy iTunes | | Music / Videos / Camera | ✅ Fully functional | | Wi-Fi web browsing | ✅ Works (via DNS or ramdisk method) | | Reboot without re-lock | ⚠️ Depends on method (ramdisk survives reboot; DNS does not) |
For years, the most reliable way to bypass iCloud on the iPhone 4s was using a specialized hardware chip, often called a "R-SIM" or an "Interposer." Iphone 4s Ios 9.3.6 Icloud Bypass
How it works: You place a thin circuit board chip underneath your SIM card. This chip tricks the iPhone's baseband into thinking it is activated on a carrier network.
Pros:
Cons:
You will see ads for software claiming to remove iCloud for $10-$20. For the iPhone 4s on 9.3.6, 99% of these are scams.
The few that "work" typically do the following:
Warning: If you flash the wrong Baseband, you can permanently kill your cellular signal, turning your 4s into an iPod Touch. Most bypass tools and methods rely on manipulating
Before attempting any bypass, you must understand why iOS 9.3.6 is special.
Why does this matter? Because successful bypass methods rely on exploiting vulnerabilities present in this specific firmware. Many of the famous exploits (like checkm8) do not work over the air on iOS 9.3.6 in the same way they do on newer devices.
This tricks the activation server. The phone thinks it has contacted Apple, but it actually contacts a third-party server that sends a fake “activation record.” This allows you to use the phone as an iPod touch (Wi-Fi, apps, music, camera) but NOT cellular calls, iMessage, or FaceTime linked to an Apple ID.
