I recently responded to a text message from my brother - it had his picture that i added to gmail contacts, so I had no reason to assume it wasnt from him. Turns out it was from a different number - I didnt notice until I had responded. A minute later all kinds of mobile numbers from the 403 area code (he's in Calgary) started responding and asking "who is this?" Anyone else had this happen or does anyone know what could have caused this? I'm wondering if my gmail contacts have been hacked??
