You will have some problems with the data sometimes by using a Tru sim with Blackberry. I have a friend who tested it and he said it worked fine but he had some issues with the data use... about AIS sim, in some countries you will have problems getting email to work.
Thanks

I just sent mine to MBK.. it is unlocked, but something is wrong because it will only make / receive one (1) call / connection after a reboot. I messed around with it a bit, but gave up and sent it to MBK. Hope to receive it back tonight.

When I worked in Thailand, I used AIS for my BB services. Can't complain much though. It just worked when it needed to. Did have some problems with the connection now and then.
