... Or my reading is correct and your proper grammar was left in Elementary School?
Your title says PSN was stuck at signing in, but you signed in with no problem after a reboot. So it was nothing more than a simple network issue you solved quickly. What's your concern?
i've had no connection problems until today. so ya once
i want to knwo if it has anything to do with the store update today
We are not there to diagnose your private network nor do we maintain the PSN servers. If you had provided us with an error code then we would know what happened. Based on the information you've provided us with, the fact that your PS3 "got stuck at signing in," can be due to several factors. For example,. your ISP, your private network, the PSN servers, your PS3 or anything else you want to add to the list.
As you have said, there is no longer a problem so just keep enjoying the PSN
