I bought this phone new from a Verizon store in January or February 2012.  It worked well at first.  I liked the keyboard.  I''ve now gotten a used iPhone 4 3G and what a difference.  The Stratosphere was freezing every day in apps and sometimes would just suddenly restart on its own.  The battery got hot quickly if any apps were running.  I had issues with the bluetooth connection in my car.  I couldn''t tell if it was the car or the phone, but now that I''ve had the iPhone I know the issue was with the phone.  The iPhone always connects.  I''d set the Stratosphere to have the Bluetooth on and the next time I got in the car it would be off again.  I''m prone to dropping things so I always get cases for my phone, but this one kept freezing so I''d have to take off the case, then the back, then take out the battery, but it back in, put the back on and the case on and turn it on again.  I also had issues with memory usage.  I couldn''t keep much on the phone before I had to delete pictures.  Therer were some game apps that came with the phone that used up a lot of space that I didn''t want and I''d delete them, but they''d automatically get installed again.  That''s stupid.  If the program isn''t required to run the phone, the user should have the option to permanently delete it, especially when the phone has a very small memory.  I had issues with the signal in my building at work.  Now, the iPhone also struggles to get a signal, but I''ve already seen it has better luck than the Stratosphere did.  The Stratosphere was also very slow with game speeds and got slower and slower and I learned that this meant the phone was about to freeze and sometimes would just set it aside to cool down.  The battery life was poor.  I carried a wall charger in my purse in case I needed to charge it and almost always had it plugged into the car charger when I was driving.  I had issues with the keyboard sliding out.  After a while it wouldn''t slide out 100% like it did at first.  Minor issues, but still one issue in a long list.I wouldn''t buy this phone again.
