The reason for the outages is because it is highly rumored that VZW is overlaying its ENTIRE CDMA packet core with a hybrid CDMA AND GSM/LTE packet core both for soon in-bound international LTE roaming (the reason VZW lusts for in AT&T: AT&T's in-bound international roaming revenue from GSM/UMTS/HSPA+ from international travelers to the USA and other rural/regional providers but mainly the international due to technology). This is bound to happen with some hick-ups I presume. Going forward I expect less and less. The overlay is legacy CDMA 1X voice and soon 1X advanced with 3GPP GSM vR9 and maybe R10 in future years LTE. I will have to say the initial numbers were shoddy but the engineering HAS IMPROVED over time and with the latest phone/air-card firmware upgrades they have been running mostly stable. The Thunderbolt will be getting a firmware upgrade within the next 10 days if not already that will fix all the LTE/3G connection issues. The reason the t-bolt dropped to 1X is because of a legacy CDMA and GSM LTE integration issue that VZW is fixing in the network.
