Next year I will be traveling a lot between London and the U.S. so I am looking for a cellphone that would work well in both countries. I was thinking maybe a blackberry or a T-mobile sidekick (?) Any suggestions / input??

Features like e-mail and text-messaging aren`t really a major factor. I am just looking for the phone that will have the best service in both countries and if possible China and Korea also.

Also, what is the difference between tri-band and quadband connection? Do you know what countries T-mobile covers under tri-band vs. quadband.

Thanks!

you can't get a phone to work in great britain, u.s., china, and korea. a gsm phone would work in all the countries except korea because they use a type of cdma. anyway you need a quadband if you are going to use cingular in the u.s. because they use the fourth band [850mhz] but if you use t-mobile a triband will do fine. if you use a t-mobile triband you can definitely get it to work between u.s. and great britain. i also suggest you get a sim-free phone so that you don't have to use t-mobile. like if you went to china, they don't have t-mobile there so you would have to get a sim card from a chinese cell phone company and put it into your sim-free phone to work.

you can rent sim cards in korea, you can rent sim cards anywhere, they have services in all countries for that. korea does have a gsm network, so basically any unlocked imported triband phone will do fine.

that's strange, my friend went to Seoul, Korea last year with a quad band GSM phone and it couldn't get a signal anywhere there. But he did say it worked fine in Vietnam and China though as expected.

Anyways, you don't want a Sidekick since all it can do is email and txt msg (it's not a phone!). A Blackberry should be fine because all current models are quad-band. What you want to do is call T-mobile after you get it (assuming you bought a T-mobile branded Blackberry) and ask for the subsidy code aka unlock code so that way you can travel with your phone and use any sim card you want.

oops, my bad. I confused the Sidekick with Cingular's Ogo which is txt and email only. I stand corrected.

no roaming agreement over there then. Ok, it makes sense.
