So Network Vision is slowly but immensely improving the overall experience on Sprint. Luckily living in the Bay Area a large amount of this work has already begun and is continuing each day. For a while I was seeing improvement and loved Sprint for every moment. At the begging of this week all of this suddenly disappeared, being an avid reader of this site I assumed it was an upgrade and just continued on with my day. Now it's near the end of the week and no improvement whatsoever. Basically I would like to know if this is a device related problem (iPhone 4, iOS 6.1, PRL 51094) or if it's an network upgrade which I'll just ignore.
I agree. I think the spectrum is much better used for LTE or 1x than EVDO.
Hopefully they will improve their handoff settings soon, though, because I drop from L1900 to CDMA (skipping L800) far too often for me to feel confident in VoLTE working reliably (at least on iPhones).
