i have song on my iPhone that i got from computer "A". There are some songs on computer "B" that i wish to have. (transfer is not possible as computer "A" was sold). Now if i want to add the songs on computer"B" on top of the currents songs that i took from computer "A" as soon as i sync my phone with "B" it deletes the music from my phone just to add the computer "B" songs. Noo! No ! No! Os this another Apple screw around?
