It's not that hard to get in the IT field prior to getting a degree. I can attest to that first hand. The problem I've seen is with some students who when I tell them the "secret" they don't think it's worth it.
Here's my "secret" that apparently isn't worth it to some people: get an internship. I started at my company at 18 years old working 20 hours a week @ $10/hour as a Server Administator Assistant. About 10 months later I found an opening in the department (which I got the first interview for because I was "in-house") I am currently in now and at the time I jumped from 20 hours a week @ $10/hour to 4 days a week @ ~30k/year base pay (not including any bonuses, differential, benefits, etc...).
The plus to an internship is also the resume experience you can put down (like my 1 year of windows server administration, remote troubleshooting/suport, etc...) which even if you do it while going to school full time that's still 2-3 years of in field experience after your degree.
Now of course, $10/hour is nothing. Hell, the people at my school are making that working in the food industry and get double the hours and a flexible schedule (my company works around school so you set your schedule pretty much as an intern which is easy to do with a max of 20 hours, which is why most people laugh at the idea and would rather try to get a job with their degree and 6+ years of customer service experience.

But seriously, if there's one thing I can say here that the members of this board listen to, it's aim for internships unless you enjoy phone support (which some people do, don't get me wrong, it's just a stressful job most of the time).
And as a shameless plug, if you live near Tampa, Florida or Southfield, Michigan I can refer you to some intership or other entry level job openings for my company if interested.
