I've taken note of the provided key and text.

The key is 'for ios download BitComet 2.03', which suggests that you're looking for information on downloading an older version of BitComet (version 2.03) specifically for iOS devices.

As for the text, it appears to be a description of BitComet's features, including its support for various file-sharing protocols, plugins, and optimization options.
