good question, I want to know, too.
@Andlaw: Can you give me download link for dark Gapps please?
The problem is, I saw that dark gapps were not installed. So I rebooted into recovery and flashed them. After that it ended with bootloop... What about the recovery when rebooting using the power button? Is this safestrap? Maybe that cou7ld be the reason for my problem..
I'm not at home or I would get the link. You should have no problem however finding it if you do a search using google, Gapps-ics-20120422-signed.zip
As for the reboot option, I believe the recovery option does not do anything "or at least it doesn't using safestrap" yet. The normal reboot option should only reboot the phone, in which case bootstrap auto puts you into cwm. safestrap you have to hit the menu key to enter recovery when the splash screen pops up.
