Mobile phone frequency spectrum allocations
I would be most appreciative if suggestions could be offered to any sources of information on the following.
I am researching mobile phone frequency spectrum allocations from 640MHz through to 3GHz.
My requirement is to locates sources of frequency spectrum allocations for devices or applications other mobile phones within the 64HHz to 3GHz ranges.
Thanking you warmly.
What is an RF classification, who sets the standards, and where would I find these classes on other phones? A lot of folks that buy/use phones here (myself included) live in rural areas and I'd love to be able to quantify for them how well their phone is going to get a signal.
Does anyone have information on this?

Building a cell phone.
I was reading an article on some website about people who wanted to build their own cell phones and such. Is that possible?
I don't mean so much as in "can it be done?"... Because I am sure that if one has access to the various parts that they could BUT are there rules about such things? Do they HAVE to be regulated? If anyone has any info please respond.

Looking for phone with Wireless Village and XHTML Support.
I am looking for a phone with two required features:
1. Wireless Village (also called Mobile Instant Messaging and Presence Initiative. News article:
2. XHTML support
I have found a few phones from Nokia (6820), Ericsson (P900), and Motorola (V600) that satisfy these requirements, but most of them seem to cost more than $300, which is a little beyond what I was hoping to spend. I won't be able to sign a contract, so I can't advantage of any price-reducing discounts. If anybody knows of any good phones that don't cost so much, please give me pointers.
Thanks in advance
Thanks in advance!

text messaging app: how to receive msgs via a phone #
I’d like to set up a text messaging application where I can receive text messages on my server via a phone #. For example:
• I advertise: send a text message to 800-555-5555 to sign up
• User sends a text message to the above number
• The user’s text message is received/processed by my server side application
I’ve heard that this can be accomplished via a Nokia phone and some kind of serial connection to my server. However, I’m wondering how it’s done on a large scale – like by TV shows like American Idol. Is it through a particular configuration in partnership with the wireless carrier - or is there an easier way?
Got Philips phone? Please try this test
We have a Java game called Mayhem's Magic Dust that we are porting to MIDP2 handsets. If you have a Philips phone (like a 355 or any of their MIPD2 handsets) please point your phone's browser at http://www.infinitelives.tv/MMD/dist/midp2.wm l and try our speed test.
It is only 72K, takes about 20 seconds to download (in the U.K.), needs only about two minutes to run as fast as it can, and it will take you all of 30 seconds to post the "ms/frame" number here (or email to firstname.lastname@example.org)
