Spoke to BB Support in Europe. They know of issue. I have sent them logs and was told that they would be sent to Developer. Murmurings about possible side-effect of last small update a few weeks ago! I will update when/if I hear anyfurther information.
Lately at work my PB can't find the free guest wifi signal but my ipod touch 2G can and browse the Web with no problems. I restarted my PB and it changed my wallpaper to a solid blue, what's up with that? It was working fine, I haven't installed anything new. I was enjoying browsing the Web at work but not anymore.
