Listing GPA on Resume...

So I'm just updating my resume, and have stumbled upon a problem with my GPA.

I was in a different University program prior to this year, and so am having a little bit of conflict over what GPA to post on my resume. Cumulatively (since I started at the University), my GPA is approximately 3.7 (plus or minus a bit, depending on what I get as final grades this semester). In my "new" program, I'm at a 3.6 (just based on the previous fall semester). I switched from Physics to Engineering, so although they're not identical fields, they aren't super unrelated either.

There's not a huge discrepancy with my GPA either way, but is it more appropriate to list a cumulative GPA, or just my current program's GPA? I asked at our career centre, and they didn't have an answer for me, and so I've ended up here.. Has anyone else had experience with this?
