One of the biggest choices you face after deciding to get a new iPhone is what to do with your old iPhone. Instead of tossing the device into a desk drawer or flipping it into a recycle bin, consider these options:

1. Voice recorder. Turning your old iPhone into a pocket voice recorder, instead of using your primary phone to record notes, interviews and meetings, means you won’t have to worry about missing important calls or messages. Top voice-recording apps include Dayana Networks Ltd.’s Voice Record Pro (free) and Voice Recorder (free, $1 upgrade) from TapMedia Ltd.
