Hi all,
I just unlocked the Orange Treo 600 flashing the 2.09 FW as described. The phone works with my provider's SIM (Mobitel, Slovenia), but I discovered a big BUG: when I call someone and press the hangup button (either with 5way navigation button or touchscreen), Treo says "hanging up", but the ring tone is still there and the other phone still rings for about 60 seconds! And the phone hangs during that time - no control works (except reset of corse).
It is simply impossible to hangup the unanswered call. What's even funnier: if the other party does answer during that time, the call IS disconnected (is it should be right away). The ongoing call on the other hand, can be hanged up without problems. I guess this is just some SW issue?

My Phone Info is:
FW: 02.09
SW: Treo600-1.0-OUK
HW: A

Also, I have no problems using PIN (like somebody had) - I can enter the PIN and phone works OK.

Another thing: is there a way to get rid of the Orange software? I noticed some people's SW version is INT - guess this stands for International.
