On my desktop I went to the gmail server and was pleased to discover that I could turn off IMAP and make POP3 the default. Everything was as advised, but sadly when I deleted my gmail account from my phone and re-installed it, selecting POP3, it came back as IMAP. grrrr seems there's nothing I can do. Either gmail or Bluemail is insisting that I use IMAP, no matter that I have now disabled IMAP.
