@Shinty: Please see the instructions below, as noted in section 5.5 of the terms and conditions of the Upgrade Program.
You will be provided with prepaid return packaging materials to allow for the safe return of your Existing Handset to MTR. Please do not return your Existing Handset in any other packaging, for example, your new Samsung Galaxy S Series handset box. You must ensure that the Existing Handset is sent to MTR within 5 working days from the receipt of return packaging materials in order to meet the terms of the Upgrade Programme. You must continue to keep up repayments on your existing credit agreement until such time we have confirmed to you that MTR has undertaken the inspection of your Existing Handset and we have accordingly settled the outstanding balance on your existing credit agreement. Failure to return your Existing Handset within the defined time period will mean that we will no longer be able to settle the outstanding balance on your existing credit agreement. You must then continue to keep up repayments under your existing credit agreement, as well as any repayments under the new credit agreement you have taken out for the new handset.
