Based on this post:

>>>

What I can tell from the FCC files for the i-900 Internal Photos at https://fjallfoss.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout =500&calledFromFrame=N&application_id=476604&fcc_i d='A3LSGHI900://https://fjallfoss.fcc.gov/oetcf/eas...'A3LSGHI900 is that Samsung is using a Qualcomm RTR6285 for it radio which according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device" Qualcomm News and Events - Qualcomm Announces World’s First Single-Chip, RF CMOS UMTS Transceiver with Integrated Receive Diversity and GPS.
So I think that it will be a matter of firmware update to have it working on any UMTS.
I hope this helps, based on this I went ahead a bought my Omnia! Can't wait to have it!!

>>>

It is very likely that the I907 will just be an I900 without a front mounted camera and with different firmware installed.

Hopefully someone smarter than me will find/cook/combine the firmware necessary to put enable 3G on the I900

Just because the qualcomm chip supports it doesn't mean the rest of the device does....

I was kinda thinking that a specific ROM would do the trick as well. If the guts can do it why wouldn't the device be able to with a proper ROM applied?

The obvious other bit of hardware that is different is the aerial - but I'm sure there are others.

pidsw -

I'm with you on this. I'm in the U.S. and with AT&T.

From what I'm hearing, the Samsung Omnia will now slated to be released as the Samsung Mirage here in the states. This is "supposedly" able to tap into U.S. 3G.

Im hoping there is a wizard out there who can figure out how to enable/tap into AT&T U.S. 3G networks for the Omnia i900. EDGE is pretty good, but need the speed for the Sling Mobile Player.

Based on the internal diagrams of the I900 there are at least three Antennas:
One for Bluetooth.
One centered on the 850 Mhz frequency
One centered on the 1900 Mhz frequency.

Given that this is exactly what AT&T uses for HSDPA and this is what the Diamond and many other world phones have, I find odd that the I907 would have anything different. (Although I have not seen the internal photographs)
If the design was only for Europe and asia I would think that they would use aerials centered on the 900Mhz and 1800Mhz frequencies, or possibly the 2100Mhz frequency.
From what I have seen, Handset manufacturers only design different internals for different areas if they absolutely have to.
Building chipset designs is expensive. As are the fab plants to create the designs.

Its entirely possible that all Omnias are actually dual-band UMTS, and not supporting all bands now simply because they are not licensed too.
Then it could be possible that Samsung will just unlock the american band when Omnia will pass FCC certification in US.

It was similar story with HTC Diamond (though here it was with GSM band being ROM-unlocked).

QUOTE(Apo11on @ Nov 1 2008, 05:19)

I'm starting to believe it might actually be possible to tweak existing radio firmware to unlock UMTS 850/1900Mhz bands using already embedded secret debug menu from Samsung developers, rather than having to dump it, reverse it, patch and flash back. Here is the secret code to access Root Debug Menu on Omnia: *#197328640#

(All the sub-menus are also accessible directly using similar codes. I've posted rapidshare link to a couple of files that contain those codes, as well as very useful
registry tweaks, at the end of this post. Please mirror it, as I used free rapidshare account, good for only 10 downloads)

Anyway, option #4 "UMTS rf nv" has sub-option "umts rf nv write", which I think allows to modify the active UMTS bands in the radio. Assuming we have that set correctly, option #9 "Common" from the same Root Debug Menu has sub-option #5 "WCDMA Set Channel", which allows to specify downlink channel range.

Here is my idea: some devices, such as HTC Diamond with US 3G enabled radio, have the same Qualcomm chip as Omnia, and run the same WM 6.1 OS. So,
I'm thinking it's worth a shot if someone with US enabled HTC Diamond provided us with settings from his device for those 2 configurable menus I just mentioned. If you backup your own settings, so you could restore them if it doesn't work - I think trying settings from another device will not fry the radio, worst case scenario transceiver will just shut down and be offline until settings are restored.

Here is the link for the stuff i mentioned:
http://rapidshare.com/files/159576760/reg.....menus.rar.html

By the way, I would have started a new thread for this issue as it fully deserves it, but unfortunately it looks like I don't have forum privileges to do it.

Is anyone out there able to help apo11on?

I really would love 3G in North-America.

Trust me on this. It is just a matter of time when a US ROM for 3G data network will be ported or cooked by several excellent contributors on this forum. Why? because coming from a RF and system background, if the HW is ready which I strongly believe Qualcomm chipset can do (just the analog front end and its common Rx architecture), the register bit settings in the FW can be tweaked properly to either support all 3G bands or any of them. It is a wide-band Rx chipset and the FW is there already, just enabling this and disabling that with some optimisation and there we go.

I got this on the "we can now cook custom ROMs - what do we want in them" thread, but I also foun it on XDA here:

Do you think this venue is worth investigating?

Don't call me that. And no - no HTC Diamond users give a damn. It would take less than 2 minutes to look up those settings I requested on their device, but even though this info request has been posted on several forums no Diamond users replied.
Personally I'm not gonna wait for 3G forever, new cool phones come out all the time, and if something like this:
http://www.akihabaranews.com/en/news-16961...ean+Market.html
hits Verizon any time soon - I'm gonna switch to CDMA and sell my Omnia. Without fast internet access half of the features of the device are useless...

I agree - won't wait forever. Unfortunately can't switch to CDMA as I have a data plan 3 year contract with fido here in canada...
Sorry, but how is one supposed to refer to you? If not by your user name?

if you can afford to buy phones like omnia you can definitly afford to pay get out of contract penalty, it wont be nearly as much. I have AT&T contract too and I have no problem breaking it if I have to.
Oh, and you didn't call me by my user name - you misspelled it and that's why I said what I said.

I really dont want to switch out of AT&T though... I like the roll overs lol and most people i know have it so it works out better for me.... Im still trying to find those settings for you i haven't forgotten.

I would guess that the fastest path to 3G on the I900 is one of:
Rip apart an I907 ROM, combine it with an I900 ROM. The hardware is almost the same internally and the Kitchen is almost compatible. The ROM formats are identical. This is an AT&T Phone and there is a kitchen for it.
Find an I900L ROM. These devices are on currently on the Venezualia Samsung site but I have yet to see a ROM for them. I don't know that they are on sale yet or when they will be.
However, they look identical to the I900 but they have 3G on 1900 and 850 as AT&T does.

I think that Secany has seen one but he has not gotten his hands on on.
