A program to change your ESN/phone quickly?

[ScrapMaker]

I was just thinking, that when I get the Touch Pro, there will be times where I would want to bring my current Touch, because of it's size...

Now that Sprint users can change their active ESN online, how hard would it be to create a program like nueMinutes, or sMMS that logs in, and changes this for you?

You could have the program on both phones, and get on the currently active phone, and quickly select your other phone...

This could be invaluable to people with multiple phones... Imagine waking up, and just transferring service to whichever phone you wanted to use that day... no hassling with Sprint's website... (assuming you even have access to a PC at that time...)

Is there anything like this, or someone willing to come up with something similar?

Thanks!
