WW now has a mobile web site where you can calculate and track your food and activity points. It is set up to work with iPhone, BB, and WM devices. I have been using it and it is really nice. You are actually accessing the Planner on the web site so all entries are immediately updated. It has some limitations, but it is wonderful to be able to track again without carrying a second device in order to access the WW On-The-Go application. IMHO, this is a much better way to track. It is free to eTool subscriber but you will have to have a data plan.
Just type
http://m.weightwatchers.com or
http://mobile.weightwatchers.com. Be sure to take out or omit the www. Some users are having success with the longer address and some with the shorter.
