First problem I've noticed: when using the dialer with the keyboard open the numbers are wrong. if you press 1234567890 you get 7937898467. If you press the alt button before each number, as in ALT 1, ALT 2, ALT 3, ... then you will get 1234567890. Double pressing the ALT button, as you normally would to lock the keyboard to the ALT options for each keypress does not work and gives you 1937898467.
Eeeek! You gave me a headache with that one... numbers make me angry
About the alarm clock, maybe it has to do with am/pm being added on? Has anyone tried pushing back the clock.apk from last nights build or trying a 3rd party alarm like klaxxon to see if it works? Its late but those are my guesses right now...
