So, I now have a 4s to compliment my iPad. I want to use all the toys I can. I'm 100% positive others know more about tying the devices together than I do...so why not ask the experts, right? For a couple years I have used google to keep calendar and contacts synced to multiple devices. This is still acceptable, both get multiple calendars seamlessly. My iPad is wifi only, but iMessage is fine...only for other iOs users I assume. I was wondering it uploading pictures to iCloud would make that more automatic to have one place to put pictures and have them show on both. I have iOs5 on both, so I could just set up wifi itunes sync I suppose. Suggestions? What else should/could I be doing to make things a better experience? I haven't tried yet, but will my apps sync when most are iPad version? Would I have to re-purchase apps? Can I have game progress sync? edit-removing the hotspot question. Found it.
