Something I’ve noticed about Apple’s ‘Remote’ application for the iPhone and iPod Touch, is a setting which lets you choose to keep the remote connected to your computer, so it doesn’t need to reconnect again when you wake the device or reopen the application. And yet, it seems to be a rather standard App Store app. It sure would be nice if some cunning coder found out a way to sign applications THAT way… If apps ran unsandboxed, and could simply be installed through iTunes, that would sure be a nifty system indeed.
Update: Looks like I was totally wrong on this one. The ‘Stay Connected’ setting only keeps it connected while asleep, not while using other applications. It always disconnects when you press the home button. Darn.
