#2: See above. For some reason this won't work. However, we have heard that if you can get hold firmware for the 7230 customized for each network operator it WOULD work. We are still trying this (no one in our IT team has had the time right now). In theroy, you would get the unit SIM unlocked.... backup the data on the unit (all via USB, so quick). Use the firmware installer from the network you will roam on. Once that firmware is loaded, restore the backup. Use the SIM on the roaming network.
Some caveats of what we've noticed. The device hardcodes in the firmware how to provision the service book for the first startup. This can't be replaced via user editable inputs as they are locked. Once it provisions on the network it updates the service books. Plus I would assume that the account with the other networks SIM would need to be for a blackberry device as some networks block access to the blackberry.net APN unless the account is for a blackberry device. In our test we're going to use a T-Mobile US blackberry and try to convert it to a T-Mobile UK blackberry. (we also use O2, but they've jerked us around on upgrading units)
Any other questions let me know</font>
Thanks for the write up Nick 1K! Much appreciated.
I'm going to try to get an Orange (France) 7230 since I've read they are releasing them here. I was a bit confused with your second explanation of changing the firmware and service books (as I don't know what either are!). I'll be interested if you can convert a US to a UK blackberry. But does that mean that it would be a "dual" US/UK blackberry or would you have to manually tweak it every time you crossed the pond?
