After a few seasons trying to use the Globalstar system, we gave up on them, and used nothing but Iridium phones.MTV

Yes. Strategic considerations are why the primary Iridium ground station is located in Hawai'i.
As a side note, be aware that all Iridium calls are treated as international calls. This means that 1-800-WX-BRIEF does not automatically connect you to a FSS in your area. This may or may not make a difference in the lower 48 with Lockheed Martin running everything, I don't know- but here in Alaska where we still enjoy local weather briefing and flight services, you really need to carry and use the local exchange numbers to call FSS on an Iridium phone. I learned this the hard way years ago when I got a FSS guy in Long Island who claimed he could close me out, but half an hour later my wife gets the dreaded middle-of-the night call about my flight plan not being closed. Fortunately my second call had been to close out my wife-plan.

Thanks in advance.
