There are several separate parts of this question. Can the Blackberry be jailbroken - yes. Will doing this void your warranty - yes. Can Blackberry OS 2.0 be jailbroken - presumably, though as best I'm aware there isn't currently a tool for doing so. Source code for Dingleberry is available, though, so feel free to modify it yourself. Will this allow you to download free apps - maybe. It won't allow you to download apps that cost money for free, but it may allow you to download apps from places that have free apps.
