iPhone firmware 2.2, two weeks on

Why is it after every other iPhone update Apple introduces more bugs than enhancements?

When Apple released their iPhone update just over 2 weeks ago, I was hesitant about updating due to past screw-ups by Apple. Despite this update not really giving any significant features (to UK owners) I decided to make the leap and go for it. Oh what a mistake this was, as like so many, my iPhone woes all came flooding back. My newly updated iPhone began to produce what appeared to be out off focus photo's when using 3rd party photo apps, the WiFi connection to my router kept failing, and worst of all I now have NO 3G or Edge connection in my house (which was OK before).

There is some good news however (but not from Apple), the photography app problems have been fixed very quickly by the app developers themselves (a big thank-you to all the developers and their hard work), although this situation should never have arisen in the first place, but where are Apple's fixes?

If anyone else is having the same problems, or different problems then please share your comments here.
