IOS 7.1.1 for iphone 4? Any improvements?

Guest

The biggest focus of this update is keyboard speed improvement, does it effect iphone 4 at all? Is it worth updating?

Yes. It contains minor bug fixes that will only improve, not downgrade your iPhone.

Will upgrading from iOS 5 to iOS 6 delete ANY data? I want to upgrade my iPhone 4 from iOS 5 to iOS 6 DIRECTLY FROM THE iPHONE using the software update option in Settings >> General. Will doing this delete ANY contacts, emails, apps, notes and calendar reminders? I'm MOST concerned about CONTACTS. I have more than 1000 of Contacts.
Why won't iTunes transfer any song or any file to any of my devices? I have unistalled and reinstalled iTunes multiple times. When I go to to transfer a song to iphone, ipad, ipod it just freezes up and doesn't do anything. I'm running the newest version of the program. What do I need to do? Just want to fix it. Thanks. I have waited on the program to transfer just to see if it is slow or what and it took 30 mins and nothing. I can't download software updates also.
What are the main improvements of each new iPhone? Could you just tell me one or two of the new features that each new iPhone (e.g. 3, 4, 4s, 5…) introduced? Thanks in advance More specifically, I'm looking for unique selling points for each (or a few) of the models - a little more detail than 'better camera' would be really appreciated, e.g. 8MP camera.
Is there any way possible to downgrade iOS 7.0.3 to iOS 6.1.4/6.1.3? (iPhone 5)? Just wondering. Is there any way to downgrade? ANY possible way? Would you recommend buying a used iOS 6 iPhone?
