Tether is an application that allows you to access the Internet on your laptop anywhere there is cellular coverage through your smartphone's data plan. No more WiFi hotspots, extra data plans or costly Air Cards! One license (29.95 $) is valid for tethering with multiple PCs. With CDMA, you can not have voice and data at same time. With GSM, you can. Tether supports tethering your BlackBerry or tethering your Android with 64 bit machines. It supports tethering with VPN connections as well as PC control software/websites like LogMeIn. The current BlackBerry Tether supports USB and Bluetooth based connections. Your device must be paired properly in Bluetooth to tether properly. The Android solution currently only supports USB.
