That Enfora solution is a JOKE! It works but is absolutely comical. It includes it's own battery and acts as a 'cradle' for the phone. You must take the phone's back off. This clips in instead. It also makes the phone MORE than twice as thick as it was before and about 3" longer. Also, it looks horribly cheesy, the plastic is awful, it's just junk. It at least includes a charger that charges the wi-fi pack and the phone but considering wi-fi cards fit on SD these days this thing is just horrid.
