Will MobileScrobbler work in the new iPhone SDK?

Here's something I've been wondering about. Ever since Apple released the roadmap of iPhone development and the SDK details, they mentioned that third-party apps can't run in the background. After avoiding it for months, I finally did the jailbreak on my iPhone last month because I realized I listened to music/podcasts constantly on the device, and none of that data was reaching my last.fm account. I opened up my iPhone to third-party apps just to get MobileScrobbler running, and it works great.

But it does the magic in the background (even over EDGE, which I optionally allowed). You play songs as normal, and every so often a tiny ping goes out to last.fm, logging the music played. I imagine that won't be possible with the official SDK but I haven't seen anyone mention this app specifically.

So mac/iPhone nerds: will I have to keep a jailbroken out-of-date iPhone to keep using MobileScrobbler come June when the new iPhone stuff is released?
