How to upgrade your htc touch P3450 GSM (SIM card) versions of HTC's 2007 Touch (Elf/Elfin) to windows-mobile-6.1 and windows-mobile-6.5


Htc touch comes with Windows-Mobile® 6 Professional O.S but you can upgrade to windows mobile 6.1 or Windows Mobile 6.5.

If you have windows-mobile-6.5 then you can get more software for windows-mobile usability.For HTC windows mobile There are few Windows-mobile-6.5 and 6.1 cooked ROMs available on one of the great and one of my favorite pocket pc.But I recommends the great ONYX ROM is one of the stable and great ROM for htc(wm 6.1 and wm 6.5).


All credits goes to xda developers please read FAQ carefully before fleshing any ROM in to your pocket pc.You have to take your own risk I am not responsible for any damage to your device.When htc-unlock and upgrade done your windows-mobile may take time to load.
