I have the Jam with an Orange Contract SIM
the 1st email connection to my ISP (BTOpenworld) takes ages but eventually connects, checks and downloads any new email
however, after that, connection and download is flakey - sometimes it is instant, other times i get the 'cannot connect to the ....' message
i have no other devices connecting to my mail box, so it's not POP locked and also, i have an XDAIIs on an O2 contract sim and that is absolutely fine
i am beginning to think its Orange GPRS...........anyone else suffering the same ???
