Northern tip of the Oregon coast is a 3g area... i've noticed the 1x since early Wednesday morning through the time i put the Tbolt on the charger Wednesday night at ~9pm.
Just changed (phone info and cdma preference through ##778# and *#*#4636#*#* or something like that) back to the original specs and 3g is up in Socal / Orange County area. Hope we get 4g back soon!
