MyWi 4.0 for iOS 4 is almost ready! and will be out later today. This new version has many new features, including battery and power consumption options that can save about 30% to 40% of battery! There is also an option to disable the blue pulsing tethering bar on top, which you can convert it into a status bar icon.
MyWi 4.0 will of course require a jailbroken iPhone or iPod touch to install and work. Stay tuned as we will let you know whenever it is ready – with a full guide on how to get it installed.
