t-mobile MDA III and upgrading windows.

[onezone]

Apologies if this has already been posted somewhere, I did look and couldnt find anything that helped.

I have the above device, and it has Windows Mobile V5 installed. if I managed to get this unlocked (the sim lock) by t-mobile, is there a way I can upgrade to Windows Mobile 6?.

Do I have to get it unlocked to be able to upgrade to WM6 ?

and whats the advantages of WM6 over 5? and will tom tom navigator still work on WM6?

Sorry, so many questions..

I'm not sure if you have read my posting properly.. I did say

"Apologies if this has already been posted somewhere, I did look and couldnt find anything that helped."

and have searched again, and still didnt find the answer, so if someone could please help me I would be very grateful.

No need to SIM unlock. Just Read up on USPL, it's a CID unlocked state you need, which is different.
Once you've run USPL successfully, you can flash any WM6 ROM of your choosing.
WM6 is faster than WM5, prettier, and generally an upgraded feel, and yes Tomtom still works.

many thanks, I'll have a look into USPL, and then its just where to find a WM6 rom for T-Mobile UK.
