A wireless system includes a plurality of mobile devices equipped with a
touch-activated `back` command input, button or soft key, that prompts
backwards navigation. The system further includes a carrier network, a
network including at least the Internet, and a server. The plurality of
mobile devices are interconnected with the server via the carrier network
and the network and are capable of communicating with each other via the
server. One or more than one mobile devices has a touch-activated `back`
command input and a memory with sufficient space for receiving a mobile
client application from the server, wherein the mobile client application
is responsive to the touch-activated `back` command input by providing
the backwards navigation through screens in `back in sequence` mode or
`back a level` mode.
