Funny question since you are already on ICS ? I can understand if you are still on GB and want to know

Sorry I cannot answer you as I never bother with these lockscreen stuffs. I just take whatever default it comes with
To me all these lockscreen stuffs are just gimmicks non productive features

That's only for Galaxy Nexus UNLESS you root and flash to any AOSP rom(CM9, ParanoidAndroid)

Use Syncmate  : found this in another android forum
It's an app for the phone and a prog for PC or Mac. The free version will sync only your contacts and calendars but they do a pro version that will sync/backup just about anything you could want - iTunes music, pics, vids etc. I used the free version.

You can sync the entire Google calendar that's in iCal (I use a Mac) back out to the phone. Google calendar only directly syncs the previous 30 days of non-repeating events to the phone. You run the app on the phone after putting it into USB debug mode then plug it into the Mac/PC, then run the prog on the Mac/PC.

I then sync'd the iCal Google calendar back to the phone. It still means you have two calendars running but at least you have access to your entire Google calendar. I still make all my entries into Google calendar and keep the second calendar hidden unless I need to check an entry older than 30 days. The other great thing is if you sync again in the same way it only adds the new entries. This sounds obvious but Kies couldn't do that either; it copied everything over creating duplicates. So, all you have to do is sync once a week and you've always got your entire up to date Google calendar available on your phone. \o/
