In Pictures: Android tethering apps, 6 excellent options

Want to use your Android phone to get your tablet or PC online? Here are five apps that'll let you share your data connection in no time.

Barnacle Wifi Tether

Barnacle Wifi Tether provides a powerful way to turn a phone into a Wi-Fi hotspot. The free app has a one-touch hotspot toggle button; if you look within its settings, you'll find options to name your phone's wireless network, set up WEP encryption, and adjust a slew of items such as the wireless channel and DHCP parameters. For $2, you can download the separate Barnacle Wifi Widget, which puts the hotspot toggle right on your home screen.

Note that this app requires a phone to be rooted in order to work. If you aren't sure if your device is rooted, it's safe to assume that it isn't.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
