The new app allows you to push changes to your calendar and contacts from your computer to your phone and vice versa.
BlackBerries have had these capabilities for a while, but now Google Sync will link up with any phone adhering to the SyncML standard. And just in case this is a feature you’re looking for, it’ll also overwrite your current contacts.
What capabilities would you like to see added? What web programs/software are you hoping to sync up with in the near future?
