I have a droid x with andriod 2.2 . And system version 2.3.15.MB810.Verizon.en.Us
I think I want to root my phone but all I really want is free hotspot service. Do I need to root to do this? And currently my phone is wanting me to install version 2.3.340.en.US
Should I install this or keep saying later. Help me please.
