Wireless Tether for Root Users
Your smartphone has lickety-split data-transfer speeds that let you play with streaming music, video and other data-heavy applications. It's too bad you can't somehow share that data connection with a laptop or other device.
With Wireless Tether for Root Users, you can. This app turns your phone into an ad-hoc (or peer-to-peer) wireless hotspot that shares your Internet connection. Then, for example, you can connect your laptop to your phone via Bluetooth or WiFi and start surfing on a big screen instead of your phone.
You can't expect broadband-level performance from this kind of setup, of course. But the flexibility and adaptability of Wireless Tether means Internet access in places that have never before seen a WiFi signal.
