Make a curve 9300 more useful.
This will be my Dad's first ever smart phone, I chose an older Blackberry because he is a millwright / welder and I figured the keyboard and trackpad would hold up better to the dirtiness of the job than a touch screen and be easier to use. I won't upgrade from my bold 9780 because it does what i want when i want and never gives me any trouble a battery pull can't fix.
So basically I am wondering if there's some apps that would assist with his line of work besides the calculator that is already programmed in. He won't browse the internet with it or even text really so hogging it's limited ram is really a non issue, thanks.
