So I have a JB on my 7.0.4 4s,and I am only gonna lose it if the performance improvements are good as I have Reduce Motion Enabled with increase contrast enabled (which disables tranparency) because otherwise my phone will stutter occassionaly b/w animations which is annoying for me...So how much improvement 7.1 has over 7.0.4 for iPhone 4s? people with 4s 7.1 please please please reply to the thread,thanks
