PM me if anyone have good reason for the thread to be continue and I will re-open the thread.

Another point I just found out is some forumers providing unlocking services includes unlocking for BB5 phones, however success rate may vary and some risk is involve via 3rd party unlocking software. You may want to PM them for details. Search their services in GS.

Since unlocking issue and flashing firmware have been quite a concern nowadays, I will make a topic and pinned it up for any discussion about it soon.

sorry for ask a silly question, izzit if i buy a 6288 here and go UK can use..? then come back to Malaysia also no problem..? as long as i buy here..?

yes you can use it like sonic said.
who? what do you mean? 

got what you mean. well according to their services offered, there is. but how success it is or is it just some random calculator method, i am not sure?

I have look/read around too. There are a few calculators already available, but only work on some very old bb5 phones (6630 etc) and success rate is not 100%. It works like requesting the unlock codes from the network itself, but at more random calculation hence wont 100% work. And 3 wrong input will result in hard-lock of the phone.

I saw those forumers did say something about hard-lock and soft-lock services. So I assume they use those calculators then. But then it only works for 6280 and previous models.

as for '3', not only BB5, the locked all phones (SE, LG and Moto) that they supplied.
