You probably know this already, but here it is anyway:
If you open up safari and tap in the address bar, you get the option to share the url via email.
Just email it to yourself.
It's not copy and paste into notes and it's rather similar to just making a bookmark, but it might help.
There was a work around with notes...something like you use your contact list and make a new contact for each note or some such thing. Then you can sync it and have the info, just in a different place than the actual notepad.
A bit clunky but it sort of works if you need it badly.
