How do you block app purchases on a BlackBerry Torch? -Daw

You need to create a BlackBerry App World login to purchase apps. If you don't want to buy them yourself, just don't create one. If you want to prevent someone else from buying apps on your cell phone, just stay logged out of the app world.To do this, when you're within app world, go to "My World" then press the BlackBerry button and select "log out." If someone wanted to buy apps on your Torch they would need your BlackBerry app world password to login.

What can you do with a 2GB data plan? -Mdgrlio

There are a approximately 1,000 megabytes (MB) in one GB.Though it might not sound like a lot you can actually do a lot with a 2GB monthly data plan. Consider this: Streaming about an hour of video on your cell phone requires about 260MBs of data, while sending and receiving about 1,500 emails without attachments only uses about 15MBs of data. That said, it really depends on how you use data with your cell phone. If you like to watch YouTube videos or TV shows offered by carriers, streaming music from sites like Pandora, and uploading a ton of photos to different sites, you'll likely use the 2GBs of data. If you simply surf the web and check e-mail on your cell phone, you may not need a 2GB data plan.
