Hi,

And thanks for your response beforehand. I owned a W810i for a while (and loved it before I lost it). I need to buy a new phone. Initially I was determined to reinvest in another W810i. But after reading pages of forums about the K800/K790 series, I am now much more interested in this phone. However, I have a huge problem on my hands. I live in California and I use Cingular network (850MHz / 1900MHz), which means that K790a would be the best fit for my position. However, I travel a lot, including to Dubai where they use 900MHz. The W810i was perfect for my situation since it was quadband. The original (prototype) K800 / K790 series came with quadband chips. The production models are either dualband (K800) or Tri Band (K790), which means that I can't have the best of the two worlds (models come either in 850 or 900MHz) Is it possible that band availability is suppressed by firmware installed on the K series. Does anyone in Esato know anything about this? Is there a thread about this that you can refer me to?

K790i / K800i Cingular users, do you have any problem with reception and/or working with the cingular network (since 850Mhz is absent) ...

I would very much appreciate your comments.

K800i is tri-band (in Europe 900/1800/1900) plus 3G.

I have Cingular and I don't have any reception problem with my K790i in Iowa. But, Cingular never deployed 850Mhz towers here as far as I know--only 1900Mhz.

Whether the missing 850Mhz support is missing depends on whether or not the tower(s) in your location are 850Mhz or 1900Mhz, and whether or not your SIM allows you to freely roam onto other carriers' (e.g. T-mobile's) 1900Mhz towers.

I have the K750i, which doesn't have the 850Mhz band. I get horrid-to-OK reception in my town, but 5 bars everywhere else, like nearby cities. I hate living in small town!

I have been using a K750 for a year now and in the past 4 months Cingular reception in Dallas/Ft. Worth TX has been getting worse to the point where my phone's almost unusable indoors, and barely useable outdoors. I have just purchased a quad-band K790i (prototype) and will test it out in Dallas in the next few weeks.

Currently in San Francisco and the k750 (as well as w810 and k790i mentioned above) all get Great reception. I suspect that 1900 is dominant around here.

First of all theres no such thing as a Quadband k790i. You can't purchase prototypes!! There usually for people who beta test or contribute to the developement of the product before release; and as far as I know the K790i is already avaliable on the market.
