Please don't bump a thread when you have only just made it, it is not good forum etiquette.
People on these forums do have other things to do rather than answer new threads seconds after they were made, if you send an email to someone you don't send them another one 4 hours later asking if they have read it yet, you send them an email again a couple of days later if you don't get a response. The same applies for forums.
Ranting over, In answer to your question - I don't think that Android supports this feature as I have never seen it before on any Android device, thus I think that it would be very difficult to implement for very little reward. This also may be something that the network does rather than the phone though I'm not sure.
