[Windows Mobile Development and Hacking General] Mjammjam:
ok, a friend of mine is running this pda with bbc4 and absolutely no problems:

Universal, 5.2.1413, 17913.0.3.0, BBC4, Midget v1.0, radio rom 1.15.0.0

The thing is, I am running absolutely the same here on mine. And it does not work: The old error, it connects to RIM network and then immediately disconnects.

I was doing fine on c0rnholio's old BBC2 hack running on WM6-2.01.08-BBC ROM. After a while the pda stopped working, BBC connected but did not sync, then the whole pda was showing strange behaviour. For example, I couldn't copy or modify files anymore "access denied".

Well, what I am thinking is: Could it be that RIM is disabling us on a per-device basis? Might they be kicking devices that show odd behavior? I mean, they know with what device type, what BBC Version and also what OS Build we are connecting. While flashing all day I was reading up and found some interesting infos that were at least new to me:

"I called T-Mobile USA today because I couldn't get this working either. They transferred me to RIM which I simply gave my Blackberry Pin and IEMI number and they put me on hold for a long time and came back saying that they cannot support the device through T-Mobile USA as they did not pay for this support. The RIM person even knew it was Backberry Connect on an HTC Wizard without my telling him. He also told me that I would have to go to another carrier who supported the device but could not tell me who supported the device. My estimation is that T-Mobile Germany is the only operator with the license permissions to support the Blackberry Connect on the HTC Wizard at this time. It is Rim's backend servers rejecting the Pins from this software."

As for " I am not able to use my xxxxx@tmo.blackberry.net address therefore I am not really getting push email", have you changed the handheld in use on the blackberry.net site? It may still be trying to send mail to the prvious device you had configured for it so update your PIN and IMEI number. Failing that, I cannot use the German BB connect software for my HTC magician because the pin numbers have not been declared as valid on the uk (voda) network yet. Could be the answer to your problem to. Pin and IMEI specific to Europe and not able to register here. Like trying to use say, a Dutch Blackberry here in the UK. It doesn't appear as a valid device to our provisioning sites and therefore will not happen.

So:

1. Our device's PINs and IMEIs are sent over to RIM.

2. Based on the Cellphone Provider contract with RIM, a device might or might not be allowed to connect to RIM in a specific country.

3. Based on the Cellphone Provider contract with RIM, a device type might or might not be allowed into the RIM network.

4. Depending on our device state (AKU, BBC, OS Build, maybe BB Transport Version Number), RIM decides to like or not like us (just specific device types are allowed on the RIM network).

With what we hacked so far, we can change 4. Could RIM still kick us out on a per-device basis? Would that be realistic? If so, our PIN can be changed on the BES server, right? Would that help that?

Sorry for thinking loud, and if this might be redundant, I just started getting into this.
