Check the LCMinutes Change History for the details of changes.
Previously I plan to add data usage support, but then I found it's quite hard for me:
First, there's no easy interface to get the data usage information;
Second, the data rate charged by my operator Rogers to my prepaid plan is prohibitively high: 5 cents per page, or per kilobytes? I doubt it's per HTTP request.
While I am still looking for ways to track data usage, I am for now focusing on free numbers (service number, myFaves, etc), roaming, and long distance support.
