I have the same type of behavior:

- left center part of the touch screen is insensitive expect with my big fingers.

- i have notice a few days before my upgrade to OS2006 and the upgrade changes nothing.


- since then the situation become worst and close to be unusuable, but i like 770 too much to separate from it ...

- since a few days, i try the Nokia support without a big succes.
i still don't known how to send it back to Nokia.

- first on the Nokia site, i was redirect to a local support shop (arwac belgium).
- they have accepted it , but a few days latter, they reply that i need to contact the Nokia Helpline.

- i have already contact the Nokia Helpline 3 times. A Technical? guy need to contact me back.
- on my second call, there was no trace of my initial call.

- i have recall Helpline , today, and now it is better, my issue at least exists in the Nokia system. But i still waiting to receive a call to start a procedure.


- it seems that nobody at Nokia ( Belgium) , known what to do for the support of 770??

if you have some experience with Nokia Support, please tell us ?

Regards
