I've dedicated my old iPhone 3G as a Bluetooth audio player. It works great except for controlling the audio. I find that the previous and next buttons are too close to the play/pause button on both the lock screen and in iTunes. I often jump to the next song when I just wanted to pause the current song.
Are there any iOS 4.2.1 apps out there to fit my needs? I found Big Button Music Player, which is the type of thing I'm looking for, but the current version requires iOS 5 or greater.
Any recommendations for apps to play the music I already have on my phone, and provide a UI with larger buttons?
