Firstly, I am sorry to join your forum and launch straight in with an issue I realise this can be annoying, but I am really stuck so I hope some people may be able to assit. I will try to be concise here, its a complicated one. First thing to know is that I'm a Yahoo! Plus customer, so I pay for my Yahoo! account and supposedly, enhanced features! I have an iPhone 3G, bought just under a week ago and I have set up Yahoo! Mail on it via the pre-loaded Yahoo! Mail icon whereby the phone carries out an automated set up of mail server addresses etc. after you have input your name, user name and password. The set up works and an account is created with all my mail account sub-folders visible. However setting up via this method, the phone will only download mails from May 2008, its as though it sees these as the last 25 mails in my account. You cannot edit any server settings using this method. So I have reset the phone, tried again, etc etc etc etc but it still will only download mails from May and not even new mails will come through. So I then deleted the automated Yahoo mail account on my phone and I set up Yahoo! Mail via the "other" option and input the POP settings manually. The set up worked and I can send and receive mails and see the newest mails in my account. However using the "other" set up method I cannot see my sub folders and "push" functionality will not work either. I have called O2 (UK), they put me onto Apple, Apple said it was a Yahoo! problem. I mailed Yahoo! 3 times via the help forms, but got no response. The agent on Live Chat would not comment as he stated it was a "Yahoo! Mobile" problem. Round we go. In the meantime, since setting up the POP account on my iPhone my mailbox has crashed repeatedly, I have had to revert back to Mail Classic when on a PC, however even using a PC browser my mail interface is regularly failing to load. Surely all these matters are related. Does anyone have any advice or can anyone identify with this issue? I'm paying enough as it is for the iPhone and contract, I have paid for my Yahoo! Plus for 3 years, and nothing works. Its pretty disappointing!! Any help or suggestions appreciated! Thanks!
