To start with I would say there cannot be a better smart phone than an apple phone, I have used samsung and htc before switching over to apple, not to mention the headaches they start to give within 7-8 months of their usage be it in the form of hanging or poor battery backup or less storage spave, the time I switched over to Iphone 4 S all these problems zoomed out like anything, I have been usinh this phone for last 4 years and still I dont find any problem with its battery back up or storage space and phone hanging I have encountered only 3-4 times in this 4 years
Truly apple is a revolution
