What time format do I use?

Minutes and seconds, like 1:15, or just seconds, like 75.

Why does my iPhone not accept the MP3 as a ringtone?

iOS needs ringtones in its own format, added through GarageBand or a computer.

Can I fade the ringtone in?

Not here; use an audio editor if you want a fade.
