I have a BB Pearl 8100 and have my gmail messages pushed to my device. When I first set it up it worked fine but for the last week I have not received approximately 30-50% of the messages I receive in my gmail inbox. I spoke to T-Mobile today...we did the hard reset (remove battery), resent service books, tons of test emails (most of which did come through after the hard reset)...Their end advice was to do hard resets everyday for the next couple of days and see if the problem comes back. But I've already not received one email since then! Anyone have any brilliant ideas? I used the search function but all of the advice seems to be stuff I've already tried.
