questions on qtek update

[Guest mike_secco]

does any one know where i can get the Qtek 1.50.9.1 update or is there a newer one out?

will this update work for me as i am with Optus which is an Australian service provider?

If i am not happy with it once it is installed can i downgrade?

If you want T9 then you would be better off getting the I-Mate

update, but remember the official line is you should not play with

updates from other countries as they have their own settings etc.

If you do update you will be invalidating your warranty and as for

downgrading, it's only possible if you have the Optus ROM image

to put back on.
