I just upgraded my wife's phone to the Razr M. I decided I wouldn't root it as Foxfi would give us the wifi we wanted without the hassle of rooting. Well we just got the phone yesterday and the wifi was working, then it updated to 4.0 or 4.1 and now I can't find any wifi app that will allow me to use wifi under my standard data (we have the unlimited data package that verizon no longer sells). We go through 25-30 gigs per billing cycle on this line. Is there a good wifi solution without rooting the phone? Also, I want the fastest wifi possible, which apps are best and do I need to root the phone in order to get maximum wifi speeds?
