I've noticed so far that my signal strength is inconsistent - guessing it might have something to do with sprint's 1900 mhz towers and 800 mhz towers. Like it can't choose what to stick with maybe if it in fact is using the 800 mhz towers... I'll either have next to no signal, then all of a sudden full signal, then next to none again... but it doesn't always do this... it does often, but it sticks to one more than it switches back and forth. Speeds seem to be the same as the normal prl though. Just enjoy the occasional better signal and 3g roaming.
