If by "finance jobs" you mean investment banking then you will probably have to boost your GPA to land interviews, especially if you have your eyes fixed on a bulge bracket position. Might be a different story if your major was chemical or electrical engineering or something known to be exceptionally difficult. For humanities subjects though, the cut off is usually around 3.5 depending on school (some slack for Harvard, Wharton, MIT or Stanford). This all assumes that you are at a "target" school (the Ivies, MIT, Caltech, U of Chicago, Stanford, Williams, Amhert, Swarthmore), or at least a "semi-target" (Northwestern, Georgetown, Duke, Cal (Haas, or engineering), Michigan (Ross, or engineering), UVa (McIntire), Carnegie Mellon, and a few others).
You can componsate for a lower GPA by networking your butt off though, or by targeting middle market or "boutique" firms. That will be a bit tougher, and will take a little more in the way of balls because it will probably involve cold calling, but its a good way in for people with lower GPAs (by IB standards). Other options to consider would be private wealth management/private banking groups at the major banks (generally less competative), or corporate finance roles with F500 companies. Try to avoid back office jobs, even at a major BB like Goldman, because once your in the back office it is very hard to move to the front office without going back for an MBA.
Good luck.
