whayt I was obliquely suggesting before was that you might try doing a manual "send & receive" after switching to 3G -no guarantees, but it might kick the polling into life again if its root cause is anything similar to the problem I was describing above. Caveat - I haven't tried this often emnough to satisfy myself that it's anythng more than coincidence that the manual intervention restarts push, so don't moan if/when it does no good :-)
