I have ported a program form Series 40 to 60. Testing this program on two simulators of Series 60 provided by nokia they are

Nokia Series 60 MIDP SDK Beta 0.1
Nokia Series 60 MIDP Concept SDK Beta 0.2

Now the program is working absolutely fine on Concept simulator but its not working fine on the first one. Problem is the speed of the game.. its very slow on the first one. i can control the speed in the program and it is fine on the Concept simulator that is i can change the speed of the game... Now the biggest problem is my client is telling me that on the actual 7650 results are the same that is not working fine as on the second simulatore on my end.

pls give me any update about these simulators.
