Due to switching between iOS and Android over the years my contacts have been strewn about between all the services I use. The current situation I'm dealing with is that about half of my contacts are on iCloud, and the other half are coming from my Gmail account that I setup through the Settings app. I'm kind of OCD with this stuff so I would prefer to have them ALL on either iCloud or Gmail.
I don't know of an easy way to do this. In the iPhone Contacts app I can turn on/off two groups, the iCloud group and Gmail group. But there is no "merge" or "sync" option. Am I SOL? Apparently you can do this easy with a Mac but I haven't had access to one since college.
