Info about Pocket Tweets, iPhone, etc.

The @ symbol next to a tweet starts an @reply to its author.

If I were to click the @ symbol next to one of your tweets, @ColeFoster would appear in my What are you doing? box, and I could then complete the rest of my @reply to you.

The * symbol next to a tweet allows you to mark it as a Favorite, or unmark it if you've already marked it.

There are many different mobile phone applications for Twitter, offering various ranges of features. The basic features will generally be those available on a computer at http://twitter.com/home , though menu items (etc.) may be named differently, and features will not necessarily be accessed in the same way as on the computer website.

For more detailed information, you really need the manual or help file for Pocket Tweets, since that is what you are using.

You could also visit Twitter Help - Mobile Devices - but most of the information there is about setting up your device (which you've clearly already achieved - don't mess that up unless absolutely necessary!), and some information may be out of date (much has changed on Twitter since most Help items were written).
