Yes, I can attest to it being spotty and I don't think all sites have been deployed/optimized yet. For example, I don't think the main tower I connect to at the Paddy Hill Fire Dept. (1766 Latta Rd.) has been fully updated. But, the one at Greece Police HQ has been updated, but it seems like the signal is pointed west, which I can understand - you can see the two towers depending where you are.
But, it also depends on your device as well. My EVO 4g LTE is notorious for it's bad LTE antenna, so I can understand why it may be spotty for me personally.
