The IPhone 4S is the best phone I have ever had! Its a bit expensive but its worth every cent! Its easy to work with and there is no complication to it! Siri is amazing, It finds everything I need in seconds. The IPhone has never really let me down, and I have not gone back to apple and complained to them about my phone and I am not planning on to yet. Its the best thing I have bought, I am so proud and happy of it!
