Hope knowledge sources in this forum can help me understand what I did that results in significant non-functionality of my I730.

I upgraded to WM5, and noticed I lost activeSync capability to the cradle.
(read prior discussion re:topic in this forum, with no identified fix...)

...next I (wifi) downloaded and installed Opera Mini 5 ...and... Skyfire.
(Both were/are accessable and working (only now if I can navigate to them).

since...Lost ability to complete screen allignment set-up, under system-screen; resultingin my touchscreen being way off, to extent it miss recognizes taps or will not respond. (have not hard reset for fear it will completely lock-out during start-up.

Cannot change screen layout portrait vs landscape and/or correctly command the touch screen phone pads. (miss dial, etc.)

Most recently... lost function of both 'blue' select button' (arrow buttons still work) ...and... 'back one screen / cancel' button below; on main face.

I have read this forum for some time, and know it is very comprhensive. Unfortunately I do not know quite what I did to the device, and therefore not sure how to querry for existing knowledge within the forum; or even where to start.

I would sure appreciate any advanced assistance for others whom may have already been down this path.

Thanks in advance.
