I just recently went through a phone interview (which at the last minute also included the technical interview) for a new job. Phone interviews are rather different than a face-to-face interview, but you still want to be professional. Once suggestion I've read (if you get a phone interview) is to dress like it's going to be face-to-face.

I also agree with the others, don't let your bitterness about your current situation bleed through!

Lastly, don't try to BS your way through a technical interview. While I feel the questions asked in my technical were "softballs," I also was willing to come out and say to some "I've not worked with that, other than to install the feature" and "I've not worked with that at all" when asked about Reporting Services and CommVault Backups respectively. I'd like to think my willingness to say those things, and not try to BS my way through the interview, helped as far as getting the job.

My stand is, don't be afraid to say you don't know something, or you're not familiar with it. After all, if the prospective employer knows up front that you're not a Reporting Services guy, but you've got the basics (or more) of everything else they need, they may still hire you with the expectation of on-the-job training (Yes, I know, some employers want exactly what they list and don't want to worry about training.)

Good luck!
