XV 6800 for verizon app issues

[pdajr24]

i have had the XV 6800 from Verizon for about 5 months now. After changing my theme and adding a few applications i love my phone. BUT, why is it that everytime that i download a game file to install it says not a valid PPC app? the only game i have been able to install in Kevtris 2. Its not only the games but the IR remote controls. and until recently the Webcam programs too. I finally was able to instal Ateksoft's webcam(if anyone esle is interested, it works great with the WIFI) I am tired of downloading, syncing, and attempting to install files that say PPC 6800, XV6800 or MOGUL and not being able to use them. Is there anyone that knows why i cant get them to work? Has Verizon prevented some application types from being installed? (wouldnt put it past them.) or is there somewhere i need to be looking? Every theme or dialer or general PPC application type i DL needs about 3 different developers apps to find one that works.

Maybe its me...This is my first PPC and i was told that i should have got the TREO 755 or waited for the RIM Curve from Verizon.
