If you're replacing your old fence, can't you dig the holes pretty much in the same spot as the old ones? That way you don't have to bother with worrying about blowing yourself up. If not, I'd call the cable and gas company and they'll come out to mark the spots where the lines run.
I'd also make sure you are digging holes of adequate enough depth for your posts. Two feet doesn't seem deep enough to me, unless it's a pretty short fence. If it's about man height or higher, I'd look at digging three feet down. The depth of the holes is probably the most important part when trying to have a stable fence.
