I've been wondering if the "Touch Input 2.10" application is necessary for my current set up. I'm running BB.4, EVO theme, at custom EVO themed HTC keyboard.

From my understanding, the EVO keyboard runs as its own app titled "HTC_IME mod". In addition, the stock "android" input is always available.

So why is "Touch Input" installed on my phone? Can I uninstall "Touch Input" without affecting my current setup?
