Another thread like this, betas are not for the average user, stop complaining, yes you say you know it's a beta but I don't think you know that, you say you are going back to beta 2... stop whining.
Beta 3 is not a "step backward" for you may look that way, because you just focus on fonts, wallpapers and how Facebook looks like, this is more stable that beta 1 and 2.
And for the ones complaining about battery life, please stop, not every beta is supposed to better battery life, of all the bugs, Apple has a priority level and what needs to fix and in which order it needs to be fixed for the next beta release, and sometimes fixing one thing means it will create a new bug or new problem.
Think of fixing/building a car, you don't paint it and then do car work, or you don't put the wheels and rim before fixing the brakes, but being software many people just think "why they don't just fix this ASAP" well, you can't fix the brakes without taking the wheels off first.
Why do you talk to me as if you know what level of a user I am, and as if I'm not fully aware that this is beta software?
Get over yourself.
