We argue that while the S60v3 ROM significantly improved device stability and security against malware, it also marked the end of the “unlocked” smartphone era, foreshadowing the modern walled-garden app ecosystems.

Once the ROM was hacked, the S60v3 became the most powerful device of its era. You could install an app called X-plore and see every single file on the device.
