Htc Mobile Query

[tammyshep1950]

Hi all you clever people out there. Hope someone can help me. Now on my HTC mobile phone I am a member of some selling sites and have have several different assortment of albums. Now when people comment on the bottom of my album, for example, someone might put, Is the pushchair still for sale and how much please. Well over time there ends up lots of other peoples comments on there, and I may have sold the item ages ago but their comments are still there. Now when i hold my finger on their comments i get, COPY, REPORT CANCEL but no DELETE. How can i delete old comments made by other people. Thanks guys, know someone out there can help me. x
