IT Manager is a really cool utility for BlackBerry 10 (and BlackBerry OS 5.0+) devices from SmarterApps. It allows you to perform quite a bit of server administration from your device. They just added SSH and Telnet capabilities to the BlackBerry 10 client so you can manage your linux, unix, routers, etc from your device. Its a pretty impressive feature set though sadly it comes at a high price. There is a 7 day free trial after which pricing starts at $2.99/week, $9.99/month or $99/year (USD).
