Forgot about the crash stuff and added in this item to the above report:

Crashing on logging in - We are also tracking a couple issues that are keeping players from logging in to games after updating to the new client. For iOS users, if you're able to update to OS4 or OS5 (depending on your device) from OS3, that should do it. We're re-submitting a new client through Apple that should correct the problem for users using an older device that can only use OS version 3.

For Android users, if you get a message saying you your device is not compatible, you can download the .APK directly. For more information and troubleshooting of Android installs, please see this support message: http://support.spacetimestudios.com/...-on-my-android
