След многократни опити да си ъпдейтна телефона накрая написах едно гневно писмо до Сони Ериксон. Отговора беше следния :
Thank you for contacting the Sony Ericsson Call Center.


"We would like to suggest you to contact with one of the authorized Sony
Ericsson Service Centers, in order to install the latest software
upgrade in your Sony Ericsson K750i mobile phone. There is an attached
file which includes detailed list of Sony Ericsson Service Centers. The
list is focused on area perspective. Therefore, we suggest you to choose
your nearest Service Center.

We would also like to inform you that, you need to bring with you the
proof of purchase (including the IMEI, Serial Number, date of purchase
and the model). Moreover, we recommend you to keep a back up of your
phone data due to possible data loss during the update procedure.

Finally, we would also like to point out that the specific software
upgrade is only available from the authorized Sony Ericsson Service
Centers and not via the online Update Service.


Kind regards,
D. Theodorou
Sony Ericsson Call Center"
