It seems as though Gmail Mobile went through a serious update within the last day. The previous mobile version was quite ugly and pretty much makes you want to stay away. The new version is true to the spirit of Gmail with an intuitive interface and a nice clean layout.
This comes the same day Google announced the iPhone version of Google Calendar. It looks like Google is getting deeper and deeper into developing applications that belong on mobile devices -- it's too bad data plans, at least in Canada, will run you about $100 a month.
