Yesterday, I had an idea - with some mobile phones now incorporating a light sensor to control screen brightness, why do they not make full use of this circuitry and use if to control the volume of the ringtone on the device?

Often, we find ourselves having to set the volume of our ringtone at an anti social level so that it can be heard when buried in a jacket pocket or handbag then forgetting to reset it once it's been deployed onto the desk/table beside you at your destination - why not use the light sensor to increase the volume when the handset is in complete darkness? Come on guys, surely this isn't too difficult a thing to achieve?

Slightly more far fetched, but still a good idea I believe - why not fit an RFID reader in the handset and supply a set of stickers in the box (they could even be called "self adhesive RFID location identifiers" or geeks). The handset could then be programmed to perform different tasks when it identifies it is nearby on of the stickers, much like a laptop detecting different docking bays. Examples of the use of theis functionality could include diverting all calls to a land line number when at your desk in the office or set a profile that makes it only ring for friends and family when on your bedside cabinet.

Come on Mr Handset Manufacturer - somebody step up to the challenge and give us some useful functionality instead of more interchangeable facias or another trick imossibly small keypad!
