FileMaker Sync

[Simplified]

I'v got Filemaker 10, 11 Adv and 12 Adv. is there any way at all to have my files sync in real time on a 3G network (no WIFI because that is working for me.) It seems to me that the only way this is possible is to get FileMaker Server, is that true. I've got a Static IP Address on my Home Computer and I got Filemaker Go 11 and 12 on my IPhone. Any way at all that I can do changes to my database on the road (out of WIFI range) and that it would sync automaticly on my home computer in real time?? Please help.

Thanks

FM 12 is not compatible with earlier versions so there is no way to sync between them all (other than using an intermediate format like csv, which would be rather inelegant and very much a manual process).
