Default My speedo was perfectly accurate with 18's

Got a GPS enabled blackberry phone (highly recomend it) and it tells real time speed and direction so I figured I would test my speedomet out because I hear ours are very inaccurate.

However, with 18" wheels at 70 mph my speedo was dead on. I followed it all the way up and it strayed off a tiny bit in the middle (at 40 on the speedo I was only going 39) but it was never more than 1 mph off anywhere up to 100 which suprised me.

"weak", i don't think so and have been with them since it was gte.

the only dropped calls i have ever had are where no one has service but me and other verizon users.
i'm still doing the old tech of a tri-mode phone, hitting, soon to be gone, analog towers.

so is telenav a sprint thingy?

evansville, rings a bell.
my youngest son was in a band with willie nelson's kids and they opened for willie back in the summer of '06.
