My PMs sent from a Droid Cell do not show

[heidad01]

I sent two PMs to another member yesterday. Not hearing from him. This morning I checked my "sent items" folder and there is no trace of them in the folder or anything dated yesterday. This is the first time that a PM sent from my cell phone does not show in my "sent" folder. Any ideas?
I hope one of the Sys Admins can look at this.
