Any chance of Basic4Browsers? eg Javascript seems to have access to GPS, accelerometer, gyroscope, and BLE, so that's everything I ever use. No wait, I use Classic Bluetooth for serial link to OBD2 interfaces too. Then again, I vaguely remember that iOS is super-restrictive about Bluetooth SPP, so perhaps everybody's moved to serial-over-BLE by now.
Where my thinking was headed is that maybe this clamping down on native apps might end up backfiring on our don't-be-evil friends by driving developers and users towards solutions that are less straight-jacketed.
