With the uncertainty of when or if Foxfi was ever going to return with JB, I had finally given up and went the root route. I had put that process off for quite a long time, but personally I am glad that I finally did it. From my limited experience so far and paying closer attention to the various ROMs available for my version of Razr Maxx, it seems that most of the roms already have free wifi built into them.
I can fully appreciate the concern over warranty. I had to take advantage of it in order to get a replacement phone. However, at the end of the day, I am still glad that I finally rooted, installed free wifi, and have explored the world of custom roms. Currently I am using the Aviator rom and it works great. If it weren't for the initial loss of Foxfi, I never would have given it a shot, but now I can appreciate why people have so much fun with it. It's almost like getting a new device.
Glad that Foxfi is back but I wouldn't give up on the root idea if you have tried being adventurous yet.dancedroid
