Considering a jump to AT&T-W, but concerned about reception in the Los Angeles area.

I would be getting the MXP200 to use for phone calls and internet browsing.

Specifically, interested in knowing where any no-reception spots might be here in town... Melrose Avenue? (I live near Melrose and Fairfax.) Laurel Canyon Drive? Sunset above Santa Monica? Etc.

All responses appreciated!
