I haven't noticed that problem with my 4S. Instead, mine has started turning itself back on whenever I turn it off (unless it's charging, ironically) and running up the Usage timer even when it's on Standby, wearing the battery down at double the usual speed.|
But no 3G issues, so can't help with that!
