so i can get the incredible 2 for free on amazon wireless with just a add on, on my dads plan costing me $10 a month + $30 for 2gb data, how is this phone and battery? i keep reading it has a awesome battery but i also keep reading its battery is bad. phone is only going to be used for email, text, calling mostly with mild internet use. the add on line price for the samsung charge is $180, is that worth it or no? i was kind of looking to save money but i want to make sure my phone gets me threw the day. right now i have a evo 3d and the viberate is terrible, how is the viberate on the incredible?
