SMS messages are sent over a control channel, not the voice channel, which is pricier, more controlled and critical to the health of the network.
RF communications for a mobile telephone network are quite different from the TCP/IP networks you are familiar with. The UDP/TCP abstractions shown to applications running on top of the mobile, to make life easier to developers, are just the tip of the iceberg.
First read about the layers in a CDMA/EVDO/GSM/UMTS network and the components that handle them, and then you will understand the achievement and nightmare that is to provide reliable TCP/IP to the upper layer of the mobile software so you can rant about your iPhone and that its too slow to watch youtube.
Oh really?
My grandpa used to run and swim EVERY day. He ran (not jogged) 3-5 miles a day and all I can tell you is that his bones were in perfect shape.
You get your knees smashed if you don't know how to run.

F5 Logoff - its origins:
Remember, Notes has been around since 1973 ('PLATO Notes'), so there are some quirks in there which might seem illogical until you examine its history. I first came across Notes in 1987 before it was ever released by Lotus. Back then it was known as DEC Notes and was widely (internationally) used within Digital Equipment Corporation on their VAX network, but never commercially released.
A DEC Notes user would logon to their VAX host using a 'dumb' VT terminal. To logout, a user could use a menu option or the command line, in which case their process was gracefully terminated by the host, alternatively they could hit the shortcut F5 key. On the back of your terminal was a DB25pin male RS232 port - on hitting the F5 key, the voltage on pin#20 (DTR - data terminal ready) would drop to 3 volts. The modem (DCE) to which you were connected would respond by dropping its carrier signal which would hang up your phone line (no Hayes commands either). At the far end of the phone line, the host modem would respond to carrier loss by dropping the voltage on its pin#6 (DSR - data set ready), and the comm port on the host VAX would respond by killing the user's process. This was the standard of the time.
When Ray and the guys took their idea to Lotus, pc networking and client/server architecture was just evolving. In the absence of any standard they simply carried over the tradition of F5 logout from the DEC environment. Up till then, the nearest thing to 'groupware' was internet newsgroups or bulletin board services (typically a host/terminal topology) - at the time, F5 was a well-considered choice for a logout shortcut
Soonafter, Windows emerged and some ignoramous up in Redmond decided to assign F5 as refresh.
Virtualize the client computers with VMWare and forget about old hardware and non-existent device drivers, been there, done that. even OS/2 in experimental mode under VMWare works just fine for both client and server.

And also because it is "nuculear" the government doesn't want to touch it either.

I max out my uplink pretty often, believe me (and not using bittorrent or P2P software).
