Sony Ericsson Update Service
The firmware of the W850/W830 can be upgraded either over the air by selecting Settings / Update Service / Search for update or via the more traditional (and potentially cheaper) method of the Sony Ericsson Update Service. In order to use SEUS you will need to have internet access (preferably Broadband) and attach your phone to your PC via the supplied USB cable.
Note that the required firmware update drivers are present in the following directory after installing SEUS:
C:/Program Files/Sony Ericsson/Update Service/drivers
If you run into problems, you may wish to download and install Sun's Java Runtime Environment separately.
If the firmware update fails part way through, retry the SEUS. If the update consistently fails you will need to perform a Master Reset on your phone. It is likely that you will be required to perform a Reset All - a settings reset is unlikely to do the job. It is recommended to use a tool such as MyPhoneExplorer to create a backup of the data on your phone before performing a Master Reset. Note that you will still lose any games, themes or ringtones present in your phone's memory.
SEUS will currently install the following firmware revisions for UK phone brands:
Unbranded UK (CDA102677/95) - R1ED001
O2 UK (CDA102677/58) - R1ED001
Vodafone UK (CDA102677/51) - R1ED001
Orange UK (CDA102677/36) - R1ED001
3 UK (UNKNOWN) - R1ED001
T-Mobile (CDA102677/26) - R1ED001

A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
