1. is it possible to program externally with which 'name' given mobile will present itself to external bluetooth world ?
2. is it possible for two phone to 'speak' with each other in terms of sending info/data under (not manual) software control ?

1. If you mean "can you set the device's friendly name", no you can't. You can access the device's friendly name, however this is only really for presenting to the user. To address another device you would use its bluetooth address.

2. Yes you can use RFCOMM to create a connection between two devices and transfer bytes between them.
