I have a jailbroken iPhone 4 4.2.1 and bought the Mywi app. I wanted to connect my blackberry to it so I could share the faster network speed, but when I search for a wifi network, it says cannot be found, my laptop finds it but it is unable to connect. I tried with and without password, the same problem. However it connects perfectly with my ipod touch. Should I upgrade to 4.3 to get hotspot compatible with non-iDevices? Or Am I doing something wrong?
