We are still having problems with certain customers downloading midi's using a cod file. We can send cod files to Vodafone, Orange and T- Mobile in the UK with no problems however whenever an O2 customer receives a cod bookmark and then presses accept to download the ringtone the lnik times out. If we send the midi link as as a bookmark then the rigntoen is downloaded OK. This has also happened for other non uk networks. Is there any logical reason you can think for this?
