Voted best tethering App, MyWi is the new big thing on iPhones internet sharing. MyWi will allow you to tether your iPhone’s internet with your laptop, computer or even your iPad. It is very easy to set up and highly essential if you are always on the road. MyWi is 19.99 cents on Cydia store, there are many sources that will provide the app for free; cracked. I suggest buying it and giving the guys who made it some props for their hard work.
1- Go to Cydia->Manage->Edit->Add
2- Add the following source (http://sinfuliphonerepo.com)
3- search for MyWi and install it
4- Respring your iDevice
5- Go to your Springboard and lunch MyWi app and pick whether you want to connect to a laptop or any other Phone and toggle the connection to on
6- On your laptop or other phone (search for the wireless networks)
You are good to go
