I have a 8310 and I was using it without a BlackBerry plan (BIS). I installed several standard applications like OperaMini, LogicMail, etc. I did setup the TCP stuff (APN) and it all worked. I was able to use Opera and LogicMail. Then after a few days it just stopped working. Neither LogicMail nor OperaMini would connect anymore. The stranges thing is that I did not do anything in the meantime. I know, because I was in the woods
. I checked my mail (before going into our camp where we have no reception) and it worked then I tried to check it again in a few days and it never worked again. Needless to say I did not install any new software between the two tries (though I don't know how it could break the whole phone).
What can I do to get the TCP connection working again? Has anybody heard of anything like that before?
