Sent a text message to my cell number with "Hi :P" 20JAN2013 at 1501 EST.

Same here. Recieved a text that said "Hii! : P" No response when texted back for identification. Called and reached a message that gave me no info on the caller but that they would be notified of my call. Jack wagons.

Received the same message "Hii !!" I replied "who's this then received 2nd text "How about we talk on Yahoo msngr screen name is audreyflirty57". WTF? 01/21/13 2:30est

yea, i just got that too. guess i should have researched before texting back...

Same as most of the above. First message was "Hi ;)"

Responded with: "Who is this?"

Responce: "How about we talk on Yahoo msngr screen name is elizabethflirter47.

Interesting.
