Depends on the company, AT&T ppl tell me is awesome but they won't let my uncle use data he pays for becuase its in a remote area(next to a cell tower) and signal for him sucks. Verizon is the best and they know it so it's expencive. My Uncle is switching to Verizon and I'm switching to T-Mobile supposlly great price vs usage.as for phone, Iphones seem to be all that amongst the teens, mostly becuase there spoiled and they don't have to pay for it. Droids similar basis just different company, BOTH IPhone and Droids are the best data phone but expencive. IPhone is more userfriendly and easier to learn although droid and spend there time on quality by making features even IPhone FIVE doesn't have. Five generations and still nothing, As for black berries, heard nothing but bad knew about them. Sadly data phones will be the only phone with in a decade so if you ONLY call and don't use data your screwed. I recommend Droid over IPhone just becuase they seem to be actually trying to make a new phone and not just moving the head phone jack.. as for "bricks" that can only make calls and maybe text.. No idea sorry!
If you want durability in a touchscreen smartphone, I have an LG Enlighten and it has lasted throught hitting ceiling fans, concrete drops from my pocket while riding bikes, bouncing on gravel/concrete, and others. The screen is still not cracked and is mainly water resistant.
