Last week, Microsoft started to send out a software update for its Windows phone 7 customers who own unlocked devices, and announced that it would take some time before all handsets are upgraded to the new firmware.

The software update comes with some appealing enhancements, including the addition of Copy&Paste capabilities, improved performance in applications and games, better Marketplace search, and more.

Those who would like to have the new software update on their Windows Phone 7 device as soon as possible can now force the update as long as they own an unlocked handset.

This is not an officially approved process, and those who would perform the update this way would do so at their own risk, since the technique is not 100% successful.

However, in case there are some who own an unlocked device and would like to try this update method, they would need to trick the device into believing that it is being used in Eastern Europe.

For that, a special phonebook (.PBK) file is required, for a Hungarian server, which can be found available for download around the Internet, as the guys over at XDA-Developers note in a recent post.

As stated above, there are great chances that the process won't succeed, and it seems that that it's almost certain it won't work on handsets like the Surround or Mozart.

Apparently, the update process would require the following steps:

- Download the .pbk file, open it and connect to EUROIP PPTP Hungary with USERNAME: demo PASSWORD: demo - Connect your phone to the PC - Disable WLAN in your phone but be sure to have FLIGHT MODE off - Start Zune and keep it running all the time - Switch to your carrier settings on the phone - Manually search for an update within Zune - After a few seconds (about 10-15 seconds for me) disable data transfer on the already opened settings tab on your phone --> The update shows up!

Additional info on the forcing of this software update for Windows Phone 7 can be found on dawnrazrblade.blogspot here, or on the aforementioned thread on the XDA-Developers Forum (via Pocketnow).
