Want 4G speeds? Don't ask AT&T (NYSE: T). Responding to a complaint filed with the Better Business Bureau earlier this month, the carrier admitted to suppressing a feature that would allow an ATRIX smartphone to connect to a higher-speed network.

"The ATRIX is a HSUPA-capable device, and we currently are performing the testing and preparations necessary to ensure that, when we turn this feature on, you will continue to have a world class experience," AT&T said in its response to Dallas-area customer Keith Geissler.

Translation: Sorry, but we aren't ready to give you the fast upload speeds we promised in our advertising. Oops!

To be fair, AT&T isn't the only one struggling to cater to data-hungry mobile users. Last month, Verizon (NYSE: VZ) said it would throttle speeds on those with the largest on-the-go appetites in order to better handle the volume created by tens of thousands of new iPhone users. Clearwire (Nasdaq: CLWR) has also been criticized for failing to deliver fast upload speeds on its WiMAX network.

So neither Big Red nor the Big Blue Ball nor any of their peers are ready for 4G. For users and investors alike, this means facing an uncomfortable truth. Much as we dream of on-the-go broadband, the reality is that it's probably months or even years away.

Sorry I can't be more reassuring. Take heart in knowing you aren't the only one struggling with the Ugly Truth. From an old favorite of mine, A Few Good Men:
