As someone else said, get off your high horse...
because the first thing I do when I download an iOS beta is run to the forum and write "WiFi Works!"
Of course if a small percentage of people were having problems you see reports back to back
And if you are so smart, why release a gold master to testers at all instead of the general public? GM's ALWAYS go through the beta testers which is proper procedure.
My high horse? Sorry, I guess I had higher expectations for a device OS that represents $50 billion for Apple!
And why would they release a GM to developers? Um, I don't know, maybe so they can build/update applications with the new API's and get them to market concurrent with the OS release? Just a thought!
