Has anyone here setup using two iClouds (for two users) on one Mac etc yet? I want to know how it works. - I have my iPhone, and I sync my calender from iCal to iCloud and my contacts (Safari and my iPhone) - My girlfriend will be using iOS5 on her iPhone, and sharing my calender (which I will share) and syncing her contacts to her own iCloud (She uses Firefox) - We currently use the same address book, but with groups setup for my contacts and her contacts. After getting iCloud setup on my iPhone last night, I now have her contacts on my phone too, but I just view me group (which works great). My question is will there be any syncing issues when she connects her iPhone up and it starts to look and sync at the Lion (with iCloud update) address book? Sorry this is a little confusing, basically, will this work between one mac, two iphones and two iClouds? (for anyone wondering, we use a seperate broswer because she likes to have loads of favourites etc and I just use Safari with instapaper etc, dunno why really ) thanks!
