What's the state of the art in quad-band capable Android smartphones? Essentially I'm looking for alternatives with capabilities similar to the
Motorola Atrix 4G. It needs to be carrier unlocked and support 850/900/1800/1900MHz GSM 2G functions and 2100MHz WCDMA.

I'm in Toronto, and I need to get a GSM phone unlocked. How much should I expect to pay, and do you know of any reputable place where I can get this done? (I'm fond of my cheap, but well made phone, and am wary of letting just anyone play inside it).

9-11 Technology Filter: I have never been able to even get signal on my Blackberry 8200 (GSM) within 10 seconds of liftoff, so how were cell phone calls completed from hijacked planes on 9-11? Specifically, given the prevailing handset, carrier, and tower technologies present in the Boston, NY, and DC metro and intervening areas at the time, and given the flight paths and altitudes of the hijacked planes, how were passengers able to complete cellphone calls to loved ones?

Cingular has announced it will now charge all customers not using a GSM phone $5/month, beginning in September. How can I tell if my (several years old) phone is GSM? I'd ask the nice people at the Cingular store but suspect they will be too busy plying me with new fancy phones to give me an honest answer.

I'd like to know if anyone knows of a phone that fits these requirements, or, better yet (and more useful to others), what are some good ways to track down a particular model that fits my specific needs?

British MeFis - A friend's family is going to England from the US for a month, and they want to be able to keep in touch with each other while there. She's looking into cell phone deals over the internet, but everything's really expensive.
Would it be better for her to wait til she's there and buy or rent some cell phones that would hold them for the month? How's that all work over there?
