A few nights ago I dropped my iPhone at home on the hardwood floor in my room. Everything seemed ok, I unlocked it and then plugged it in to charge when I went to sleep. The next day when I went to text someone, however, I noticed that the bottom 1/4 inch or so of the screen no longer responds (so the space bar and "send" buttons for texting are unusable among other things) and there's a pretty bad ding in the top left corner of the phone where the casing is now loose. I am using the phone unlocked on T-Mobile so no warranty of any kind

Now I'm looking for a new phone with a good internet browser and screen for under $300 USD. Any recommendations?
