Next2Friends, a mobile social network that has yet to launch commercially, has already made its first acquisition, fellow mobile social start-up BluetoothMeet, in preparation for its launch later this month.

The UK-based Next2Friends has been in beta for four months and has signed up "thousands of members across 129 countries," according to a NetImperative report.

BluetoothMeet founder Luke Rose has joined Next2Friends to head up its proximity-marketing program. As its name suggests, BluetoothMeet is a social service whose network of users keep in touch via Bluetooth.
