I rooted sgn2 and cannot get Internet connection. That was purpose to tether to my ipad. Foxfi does not work for sprint. Does anyone have an idea of why no internet after root?
I don't know about your lack of connection, but I wanted to say foxfi is working just fine for me on my viper letting me tether my nexus with no issues.
I am having trouble getting foxfi to work. Could you tell me what software version you are running on your viper (is it gingerbread or ics?) and what version of foxfi you are using successfully?
