I was looking forward to multitasking mainly for using iFitness in the gym. I always listen to a playlist on my iPhone while also using iFitness. Each time I want to change a song, I have to QUIT iFitness, change the song, then re-open iFitness, which has a very slow fade-up screen, and doesn't return to where you left off. Update: My error. By double-clicking the Home button with the iFitness app open, you CAN change songs on the iPhone without closing out of iFitness. I was clicking on the iPod icon rather than just using the playback controls in multitask mode, which closed iFitness. Sorry for the misinformation.
