Any secret to getting an internship at a premium investment bank?

I am going through the traditional online apps, but they rarely give a contact so it is difficult to be proactive. I notice that they recruit at Ivy League and Top 25 institutions, but what about the rest of us? I attend a pretty small private university with a useless career center. They could help if I wanted a position at Edward Jones, but forget it when it comes to Goldman, Morgan or Merrill. I have no contacts in the industry. Any help would be appreciated. I can't even seem to score an interview. Next summer will be my last before graduation and at this rate I am thinking I may just go to a top 25 b-school (already have work experience (non-finance), 4.0 GPA and 710 GMAT) and use their connections.

You need to hire one of those hot-shot consultants who groom and polish you and "sell" to you the contacts that can put your foot in the door. All for a price of course.
But business school, especially MBA at a top 25 require this same - "agent" mentality. You'll have to grease someones hand. All of the applicants and interns do this. There is no way around it. You either are born with contacts, or you buy your contacts.
Your grades and test scores will certainly help though.
