Excel formula

I need my iPhone to report a custom GPS location whenever I choose. The goal is simple: set any latitude-longitude I enter and have every app on the device accept it as the phone’s real position. You are free to use whatever approach you trust most—Xcode simulator, a lightweight on-device utility, or a safe, reversible jailbreak tweak—as long as it works reliably on current iOS versions and does not require extra hardware. I’m happy to install a profile, run a Mac-side script, or follow detailed instructions; just keep the process clear and repeatable so I can move to new coordinates later without starting from scratch. Acceptance criteria • iOS device shows the spoofed location system-wide (Maps, browser, third-party apps). • I can switch to another set of coordinates in under two minutes. • Original GPS behaviour can be restored without data loss. • Full written guide and any necessary files or commands included.
