I noticed in a couple of threads that people are having issues with their 8700gs where emails can't be sent or received even though the signal is on EDGE network. Plus, they would need to turn wireless off then on again to get messages flowing again. Out of curiosity, has anyone heard anything from T-Mobile or Blackberry on this? I also have a couple of users in the NYC area on T-Mobile with 8700gs who are having the exact same problem. Is this a flaw of the handheld itself?
