ok, i have found a few 3rd party apps and games that i would like to install on my phone, but every time i try i always get an error

Warnings were encountered during the loading process:
The following modules could not be loaded because their digital signatures were invalid.

and here would be a list of whatever i tried to load.

I spoke with the makers of the apps but they arnt much help.
I dont have internet access on my phone, cuz i havnt paid for it. i hate to think that i HAVE to pay for internet for my phone just to load a few apps. why wont the desktop manager work?

If these apps require you to pull from a server across the internet, you'll get an error because you don't have service. You have to have a Blackberry data plan for things to work.

why wont the desktop manager work in this instead, im given both file types to do this
