Have you gotten a new phone recently? Did it come with Bluetooth? If you don’t know, your probably going to get bluejacked at some point in the future.
Bluejacking is the “new spam of mobile phones”:http://news.bbc.co.uk/1/hi/technology/3237755.stm. The Bluetooth technology inside your pretty new phone allows someone to send you messages if you don’t secure your phone. These messages are sent as a contact card instead of as a standard SMS or MMS message. From what I’ve tested so far the receiving user still needs to accept the bluetooth transmission in order for the contact to be sent successfully. There may be some other configuration to allow messages without warning to unpaired devices but I wasn’t able to get that working without pairing the devices.
Apparently this “phenomenon” has been around for some time as searching on Google reveals numerous hits to the subject including dedicated sites such as “BluejackQ”:http://www.bluejackq.com/.
