Holy cell towers, Batman! In a stunning announcement, Verizon Wireless has promised that customers will be able to use "any app, any device" on its network starting next year. Is this the end of the walled garden as we know it?Up until today, Verizon Wireless has retained more control over its network of services and devices than its three large competitors. No other carrier had a walled garden that stood so high. In fact, many of Verizon's competitors have lowered the walls to their own gardens by a few blocks. That is all set to change.

This morning Verizon Wireless broke the news that it will let its customers use the devices, applications, and software of their choice on its network. Wow.

This is how it is going to work:

Of course, customers will still be limited to phones based on CDMA technology. This means that any device that uses the Sprint network, for example, could be used on Verizon's network instead.

Verizon says it will not change its existing retail sales channels at all, and customers will still be able to go to Verizon Wireless stores and purchase phones and services just as they do now. It is simply offering customers who don't want to be limited to the current handset or application selection the opportunity to use the device that will make them happy. Thank goodness, says I. This will equate the freedom that GSM-based users have had for years and should level the playing field in that respect.

This also is Verizon finally owning up to the reality of what wireless networks will become: dumb pipes that are used simply to access data and the Internet.
