Yes, (You sound like Slacker Tech Support, LOL!) Is yours?
Really weird; I uninstalled and then reinstalled the Slacker iPhone app and it worked perfectly on my JB iPhone. Who knows.
I have discovered today that the crashing isn't limited to just Slacker, since it's done it on a few other applications, and cover flow on the iPod. Time to hit the Apple support forums.

Could be that too. If you have enough room on the device you can pay $3.99 for a Slacker Plus subscription and cache, which would eliminate the problem.
