I have a iPhone 4 running 5.1.1. Recently a few of my apps have come out with updates requiring iOS 6. I always read-up on the new updates, and I am never really encouraged by what I read. The Wi-Fi connectivity issues, buggy iMessage and the battery life issues specifically seem troublesome. I've had varying success with updates/new Apple products, but like with most things on the internet its hard to find a straight answer about how likely you are to experience the known problems. Some articles I've read seem to say is fine, others encourage users to wait. Forums are filled with people posting about issues they are having, some are resolved others are not. I would rather not jump through all the hoops of downgrading if everything goes to hell. Equally, I would like to be able to use my apps with their upgraded versions. TL;DR: Nervous about updating from 5.1.1 to 6.1.3, is it worth it for a few apps? Any thoughts one way or another? Thank you!
