Won't phones need an OTA (software update) before then too?
The suppression signal is on the Sprint side, so no update is needed on the phone to handle the switch change.
However, the LTEvo has some sort of LTE provisioning bug, solution is under escalation, so like the Evo with its launch day update and the 3vo with its launch weekend update, I expect that this baby will continue the tradition and have a very early update.
How confident am I? Very.
