Uploading sketch's over bluetooth?...

For the last few months I've thought about this, seems easy enough since it uses UART, i could just use pins 0/1 problem solved, but it would leave an issue, being able to reset the board to actually upload the sketch.

So then..

Sending the command to reset itself over bluetooth, having the arduino fire off a pin which resets it (via a hardware mod/transistor pulling reset low/high?) then the computer can upload the sketch.

Any thoughts, possible to do this?...

It may be possible depending on the given module. Some are made specifically to support this and some kind of support this.

That said from personal experience this can be a very difficult issue, so I would try to buy a module that was built to do this or avoid uploading code over Bluetooth entirely.
