I set up my i1 using the POP3 email server(comcast) . Set up was easy and I got my e-mails initiallly. The phone works great and I have had no issues other than this.... I have sent myself e-mails several times to check this and it's consistent. I can send e-mails and they will be received within minutes even with picture files attached, but I am not receiving them or being forwarded to my i1 for an hour or sometimes hours. I have changed the account settings to check e-mail every 5 minutes as apposed to default of every 30 minutes. I came off a 8350i which had a very good e-mail system. Is this an i1 or a network problem? TH i1 is great other than this. But unfortunately if it cannot be resolved I may have to return to the 8350i. Nextel support had nothing to tell me as always.
