I am using SPRINT carrier, and an HTC HERO phone, rooted with Gingerbread. I have three gmail accounts. One default (my main one, that I sync addresses, contacts and calendars) and two others that I only sync the email sections. Problem is that I cannot send attachments from my main gmail account. I compose the email and the attachment, click send, it says message sent - but the message never arrives, and doesn't show up in my sent folder either (either the imap one or the regular one on my computer). not only that, but I find that 9 out of 10 times, if I am replying to an email in my main gmail account and click send, I get the little red "sending", and that's it - it freezes. It doesn't send, I cannot access the email again on my phone, and the ONLY thing I can do is delete it. There is no record of it being composed, no drafts, nothing - it just never existed. I have also noticed that if (when sending out test messages), if I send myself an email to my default gmail account FROM my default gmail account, it never shows up, never gets sent. So there are definitely some issues. Anyone got any ideas?
