I need information from anyone (with only a 4G Verizon) smart phone that has a Wi-Fi hot spot in the phone. This phone would be able to work 6 to 10 laptops at the same time on Wi-Fi. I need to know about battery life and drop off problems if phone is worked on 3G system and moves into a 4G system. If you have one and they are (rare), please send me the type of phone you are using and tell me if you are happy with it or not. Do (not) need information on other phone companies, phones that work with a cable from phone to laptop, MiFi, or non-smart phones.
