installing or reinstalling software on Nokia n82 and ubuntu

[Michael Weaver]

Can software such as Talks be installed or reinstalled on the Nokia N82
using Ubuntu and Orca?
I ask because I have been told that I may need to do a hard reset of my
phone because a few minutes after switching on my phone, apps are either
slow to open or don't open at all in the case of Galery as I have been
trying to find out how to take photos so maybe my parents might take
holiday pics of me.
I have been using Daisy2go as I have Talks Premium only I have
transfered Daisy Books onto my SD card via the USB cable this is when I
first noticed my phone appearing to be sluggish.
I deleted one of my three audio books after listening to it and I have
deleted the privacy information I may have stored on my phone while
surfing the web on it but I still get this sluggishness a few minutes
after I switch on my phone, the first couple of minutes or so it works
fine for some reason.
This is why I have been told I may need to do a hard reset and do some
kind of reinstall which is why I ask if this can be done in Ubuntu
similar to what I might do when transfering my Daisy books maybe.
