I suspect that the phone may handle this a bit like a mail server - try hard for a while, then decrease the frequency of connection attempts to preserve battery. So the net effect may be quite subtle.
I admire your optimism, expecting cellphone vendors to have heard of exponential backoff. Personally I would expect the base system to have it, and then for all the telcos to turn it off in their branded versions so that the phone is "more responsive"...
Why would a phone need to send anything in such a situation? Surely the cell towers always broadcast their presence so phones can passively listen to determine whether it's even worth trying to send a packet. In the usual case phones massively outnumber cell towers. So the only sane way to design things involves the rarer items (cell towers) broadcasting and the common items (phones) responding. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
