I noticed in my text messages that I have been receiving messages with the sender listed as "" and no phone number. The messages are blank but they show up in my backup sms log in Gmail as:
MMS with (No phone number):null
Also, when I try to forward the message from Gmail the message then appears below in thread of mail. NOTE: I changed my email address in pasted message below for purpose of posting this to the forums. In the message, my email is shown in the To: field
---------- Forwarded message ----------

Should I be concerned?
