Ok, I am not a developer and I bought a UDID registration for my iPhone 5S(for safety just in case if Apple decides to deactivate non registered iOS devices) and I upgraded my iPad 3 CDMA without an UDID reg. Now, granted, iPhone 5S is way faster than iPad 3, but there seems to be more crashes and more bugs on iPad 3 than my iPhone 5S, not to mention it's also a lot slower than my 5S too. 5S is doing OK, there are some bugs, but as for every day tasks, such as phone, text, and emails, it's doing really well for a beta 1. There are obviously some bugs that I encounter here and there with third party apps but that's really out of anyone's control at the moment. How is iOS 8 doing on your devices and what devices are you using? Also... how long does it typically take for apple to release beta 2? Probably only Cupertino knows.
