As stated on the FNB website:
The FNB Banking App allows you to view your account list and balances, transfer funds, make payments and get detailed transactional history.My first impressions of the FNB app have been good. The Blackberry App world allows for an easy installation of the app. On your side all you need to do is provide your banking username on the app and then login to FNB online banking and link your phone with the site. Once done you login to the App on your phone and access all the content and functions mentioned above.
The FNB Banking App also brings you additional value added benefits like the ability to access a FNB directory and make free calls to any FNB Call Centre. You can also locate FNB branches and ATMs on a map using Location-based Services.
When starting the app on the Blackberry Torch there is a little delay in opening but there is a decent splash screen and you are welcome to a nice slick and simple to use menu. All the buttons are self explanatory and the interface makes navigation very easy.
On the down side, the app is a little sluggish in changing screens and did make my Blackberry hang upon accessing the app the third time round. The phone did recover without any issues and use of the app continued. Given that I have not used the app all to much yet, my first impression of the app is that it is very good but only time will tell.
