Received the same exact text with my first name on 10/27/12.  They wanted me to add their yahoo messenger with "txtiegirl8".  Glad I found this site and did not add to my yahoo.

I also got a text from this number with my first name in it. Thanks to the previous posts I did not text back.

I got a text from this phone number: 704-550-2785 and it had my first name in the text.
When I texted back 'who is this' - they responded with this message: 'lol, if you wanna know who this is u gotta addd me on Y!ahoo msger, my id is txtflirty.'

I saw in other posts about this that they could be using the gps tracker to hack into the phone to get credit card, etc info - don't know if this is technically possible.  Will be reporting to Verizon and Yahoo.
