Digital file information about the digital file is stored on a web-based social network database. The digital file may be located on the same server as the web-based social network database or a third party server such as a mobile phone carrier. A user of the web-based social network database requesting the digital file may require a different format of the digital file than that used by the device of the member. If a different format is requested by the user, a server finds or converts the digital file to be compatible for use by a device specified by the user. ## Claims ### Claim 1 A method for distributing a digital file in a peer-to-peer network comprising: storing identification information of the digital file in a record of a first user of a web-based social network database; receiving a request from a second user of the web-based social network database for the digital file, the request based at least in part on the identification information in the record of the first user; locating a source of the digital file; and facilitating the transfer of the digital file from the source to a device selected by the second user. ### Claim 2 (depends on 1) The method of claim 1, wherein the digital file is a ringtone, a game or an image file. ### Claim 3 (depends on 1) The method of claim 1, wherein the source of the digital file is a third party server. ### Claim 4 (depends on 1) The method of claim 1, further comprising recommending an additional digital file based on the digital file requested by the second user. ### Claim 5 (depends on 1) The method of claim 1, further comprising recommending an additional digital file based on characteristics of the second user. ### Claim 6 (depends on 1) The method of claim 1, wherein the device is a mobile device. ### Claim 7 (depends on 1) The method of claim 1, further comprising ascertaining device information from the device for which the digital file is requested. ### Claim 8 (depends on 7) The method of claim 7, wherein the step of locating a source of the digital file further comprises using the device information to find a compatible digital file. ### Claim 9 (depends on 7) The method of claim 7, further comprising converting the digital file to a format compatible with the device using the device information. ### Claim 10 (depends on 1) The method of claim 1, wherein the device is associated with a third user. ### Claim 11 (depends on 1) The method of claim 1, further comprising ensuring integrity of a digital rights management technology. ### Claim 12 (depends on 1) The method of claim 1, wherein the digital file information is associated with a first user's digital file associated with a first user's device. ### Claim 13 A system for distributing a digital file in a peer-to-peer network comprising: a web-based social network database configured to store identification information of the digital file in a record of a first user, to receive a request from a second user of the web-based social network database for the digital file wherein the request is partially based on the identification information in the record of the first user; a finder module configured to locate a source of the digital file; a server configured to facilitate the transfer of the digital file from the source to a device selected by the second user. ### Claim 14 (depends on 13) The system of claim 13, wherein the digital file is a ringtone, a game or an image file. ### Claim 15 (depends on 13) The system of claim 13, wherein the source of the digital file is a third party server. ### Claim 16 (depends on 13) The system of claim 13, further comprising a recommendation module configured to recommend an additional digital file based on the digital file requested by the second user. ### Claim 17 (depends on 13) The system of claim 13, further comprising a recommendation module configured to recommend an additional digital file based on characteristics of the second user. ### Claim 18 (depends on 13) The system of claim 13, wherein the device is a mobile device. ### Claim 19 (depends on 13) The system of claim 13, further comprising a device specification module to ascertain device information for which the digital file is requested. ### Claim 20 (depends on 19) The system of claim 19, further comprising a finder module configured to locate a compatible digital file using the device information. ### Claim 21 (depends on 19) The system of claim 19, further comprising a conversion module to convert the digital file to a format compatible with the device using the device information. ### Claim 22 (depends on 13) The system of claim 13, wherein the device is associated with a third user.
