I am new to BB development. I have 2 queries
1 Is there any difference between terms BB Device software and BB OS ?
2 If an app is designed to support OS 4.5 , then would all devices running
4.5 and higher version would run the app correctly (assuming resolution
thing is taken care of) ?

Also, though BlackBerry is forwards compatible, you should still test on the different versions. It's not uncommon to write in, say, 4.5 and it works on 4.6, 4.7, 6.0, and 7.0 but not have it work on 5.0 for various reasons.

Just to add on what rcmaniac25 said, I recommend using the 4.7 compiler if you want the greatest compatibility. OS4.7 demands only touch screen input and the 4.5 API has no touch screen support. Even the most basic 4.5 compiled app with a basic user interface may cause a 4.7 device to run in something called "compatibility mode" which you probably do not want.
