Started about a week ago, just annoys me. I'm running Ultimate Droid 2.5. Let me explain it as a scenario: I'll have some emails when I wake up, notification says I have 9, So I delete them after I see it's just unimportant stuff, I get another email later that day, it shows I have 10 emails... I open up Inbox and I just see the one new email. Okay, so I delete my 10th email. Later on that day, I check my phone, 5 new emails. All unimportant facebook alerts. But it now shows I have 15 unread emails, but nothing in my inbox. I log onto gmail on my computer... There's all the emails I supposedly deleted. So I delete them, now my phone is good to go.. Until I get more emails. So pretty much I can't delete the emails on my phone.
