In much the same way as most GMail users also run the Java-based GMail client on their phones, there's now GCal, a Java-based Google Calendar client - except that this one's not an official Google product. It's also still early alpha status, but looks rather promising for those that want a lot more than Google's existing web-based Calendar view.

It includes 

• calendar filtering
  
• events creation
  
• event searching
  
• events location map viewing
