syncing iPhone's iCal after upgrading MacBook frm Leopard > Lion
after upgrading my MacBook from Leopard > Lion (OS10.7.4), thus being confronted with a fresh & empty iCal on my laptop, I hesitate to sync my iPhone's iCal (contains all data - past, present & future) with laptop - afraid iPhone's data (the only ones I have left now...) getting overwritten...
to be sure, have same hesitations as to my AdressBook on iPhone
being somewhat digi-clumzy, I would appreciate your advice & support!
