Xperia Pro/Neo/V/L :: How To Remove Affiliate Applications

I have bought in Poland brand new SE NEO V, and I'm not happy with applications attitude in this company. With that phone, has been delivered some unnecessary applications for me, like office suite or navi expert, which is not a freeware nad I must pay for using it. I want to remove them, especially the first one, but whithout root it's not possible. Why I don't want them? Each time i want to save, view image from internet browser or other applications, office suite start as application which allows me to view image, but it stays active and hidden - using my battery. If I leave it to work I must resupply power two times for a day.... which is not acceptable, as much as that I can't imagine that each time I use internet, I must enter application manager and kill tons of applications which has been preinstalled and start for my "comfortability". Rooting for me by myself is also not good solution because by doing that I lose my phone warranty. So what can I do to remove those applications?? Polish division tells me on infoline about those applications, that they come with phone and are necessary for phone working and they or I cannot remove them, and those also makes me cool so there is no reason to remove them.... Which i leave with no comment....
