I got 4 text messages of the same sort and i'm with Virgin using a Blackberry 8530. if this costs me anything i'm definately reporting this.

4 messages to my Bell Mobility prepaid samsung double flip phone.

i also own an LG rumor from virgin mobile, and i just got received a text message from (416) 555-2121 at 8:00pm in two parts containing 1st: //WDAAMAXRABXwLoABABChCK6AAyiCgQEBwMIIQUHKNDo6OB0Xl7a8uDSxujq5MrmXMTK2NhcxsJeXubQwuTKmsrm5sLOylzI3n7S3OzS6Mp63Iq05GjelJxqqqBgtG6e1tDCltYAA0Q
2nd: //WDAAMAXRABIQD4ABAIACAEKCgag0sZerNLIWprK5ubCzspAAAwGABYCA==

whats up with this???

I've just started getting the same thing.  I'm on a Virgin phone, which uses Bell's network.I Googled the number and found an obviously fake car listing (check the seller's address):http://www.autodeal.ca/category/1041/DENALI/l ... li-SUV-AWD.html

This text is an error text meaning that someone has tried to send you a photo message and your phone is not compatible with the format in which the photo was sent.

I got the same thing on a Samsung Instinct.  And only my dad has my number as it is brand new.  Got for in a row - same script as above.  Very odd.  Plus I have free incoming text - so i doubt that its a money grabbing scam by providers.
Very strange!  Even more strange is the 3 websites with this discussion about the same number that doesn't exist!
