This app seems to have really screwed up my N900. I installed it, went through the process of signing up for Ping, entered key and - like others here - just couldn't get it to work. So, I uninstalled it.

Since then however certain icons in the settings menu won't open. I wanted to configure my IM accounts since this app seemed to have left my twitter account in the availability list (but won't connect) but I can't access my account settings.

any advice on what I can do? I would prefer not to reflash as I'm a bit of a noob, but not sure how to get the device working again. I've tried rebooting a few times but it has had no effect.
