EVDO Service (Western Columbus OH)

[qbunnie]

I've been getting EVDO Service at my apartment since I got my Mogul over the summer, it has never been below 2 bars. However, as of today, I can't seem to stay on any EVDO signal. It continually switches back to 1xRTT.
I'm hoping this is a temporary problem Sprint is having with a local tower or something, but I was wondering if this is some known hardware failure with the Moguls. I couldn't find anything substantial with a quick search, but any info would be appreciated.
I'm in the Hilliard area in western Columbus. It is an EVDO Rev A area, FYI. If anybody else is around there, please confirm/deny any problems. Thanks.
