Question about Sony Ericsson W300 Cellular Phone
Hi received a phone by Fido and would like to transfer my favorite music as ringtone but it doesn't work. Please help!
If the phone is a Rogers or Fido variant then it will not be able to use user created or third party MP3 files as ringtones. This is due to the Rogers software customization, which uses DRM to restrict content use.
This uses a software restriction method known as DRM (digital rights management) to control what and how content can be used. The provider places their own software on the phone which restricts the use of MP3 files as ringtones to those purchased directly through them or limited to a size of 600kb.
Most carriers now enforce DRM, through customized software on the phones, to restrict how certain content is used. Unless a file is digitally signed with the carriers key or within some other specification set out by the carrier, it will not be usable as a ringtone.
You should contact your service provider for more information on DRM and other content restrictions they have placed on your phone.
You may still have the option to use other file formats such as midi, wav, mp4, m4a, and, unrestricted AAC.
You can also have your phone flashed / debranded, to allow for custom ringtone use.
You could also use the DRM packager on Sony Ericsson's Developer site to bypass these restrictions. It may be a bit complicated, but once you get it, it's simple.
