I recently upgraded to the 3.1.1 software on my iPod Touch. I have subsequently jailbroke it with almost no problems. The only problem I have found is that now any attachments I get through e-mail are replaced by the winmail.dat file, which obviously cannot be opened. I have tried sending myself attachments from my work e-mail, which is through Microsoft Outlook 2003 (on an Exchange Server) to test the different settings that may be affecting the attachments with no luck. My outgoing emails are set to be sent using HTML, which should be ok. I am not sure if it is the email account on my IPT that is causing the problem. It is an att.net account. Any advice???
