I purchased my Droid on Nov. 27th. I set up two pop3 email accounts & continue to have the same problem...I receive emails for approximately 24 - 48 hours, and then they stop coming through. The only way to get them through again is by taking the battery out & back in and then repowering the Droid. The same cycle continues (within 24 - 48 hours the emails stop syncing). I returned my Droid approximately 2 weeks ago & was given a replacement, but I continue to experience the same problem on the replacement. I have been on the phone at least a dozen times with Verizon & Motorola Tech Support (and even my ISP) and have had no resolution.
During my latest call to Motorola's Tech Support dept., the rep admitted that Motorola is aware that there is an issue with some pop3 accounts & they are "diligently working on the issue," but they are not able to guarantee a fix or an update. The only thing they can suggest at this time is to take the same steps that I have been taking (taking battery out & back in).
A Verizon Wireless Customer Support Rep told me tonight the reason that my Droid is not functioning properly is because I am on a grandfathered plan (Digital Choice) vs. the new Nationwide plan. I was not aware there was a difference between the two plans in the coverage/service...I assumed it was just a matter of minutes/allowances & and that I pay for calls made outside of my regional area vs. those calls being included in my plan. I'm not sure if there is any truth to what she said. The sound quality on my phone is very poor (sounds like I'm talking into a tin can), so maybe this would be the reason. I have read many posts about Droid having issues with pop3 accounts, so I'm uncertain if it is an issue with the phone or if it is in fact the plan I'm on. If anyone has any knowledge or experience with this, please let me know.
