Short of it is I am stuck with a iPhone 3G for 3 more months till I can get hold of a 4S (I don't think it makes sense to buy a 4, then a 4S in 3 months) I have an iPad and iMac that I want to update to iOS5 and Lion respectively. Obviously the 3G won't run iOS5 and hence is iCloud incompatible. I need to have the two iOS devices and the iMac to continue to sync the contacts and calendars as they do now with MobleMe. I want to be sure that if I install iOS5 and Lion, they will still sync with mobile me (and hence the phone) till I get the 4S. What are peoples experiences?
