1.4 (See all)

CheetahWatch provides you with signal strength, network mode (GRPS/WCDMA/HSDPA), network name control over your connection, and statistics about your current connection (current throughput, total data transferred, connection time). It does this through a little icon in your menu bar (and a bigger window, if you want to see it), and also helps you keep track of your usage.
