Can I send files using bluetooth to a device that is not discoverable but previously paired? I can send files using the built-in Bluetooth File Exchange on OSX Lion just fine, except it requires me to put my phone in a discoverable state. However, since this is an Android phone, it stops being discoverable after 120 seconds. In addition, I have a nice Bluetooth toggle on my home screen but I can't get one for BT and discoverable.

The Phone is paired with my MacBook, so I was wondering if somehow I could bypass the discoverable requirement for previously paired bluetooth devices.
Normally, yes. Click the Bluetooth icon in the menu bar, your phone should be listed in the “Devices” category. From there, you can toggle actions on it.
