@mike,
I'm using Curve 8900 5.0.0.1067 with Celcom on BIS Professional Lite. I'm unable to go into the engineering screen. I've tried multple times and confirm that all are correct. While tethering, i open services option and it says connected to BIS.

Mike, if we do tethering like tat wit bis too, will the bb's battery drain fast?

be reminded that if you plan to play games on PlayBook, just don't. Go buy iPad for the apps. But for superior surfing and Flash and business apps, PlayBook wins against most tablets on the market.

Anyone got good lubang for PlayBook accessories?

I got sell some acc for playbook 
1.screen protector
2.silicon case

Guide: How to Have Playbook Tethering & BIS Access at the same time

As a Playbook AND BB user, there are many way to get connect. 1 of them is tethering to your BB phone. But during tethering, your BB will disconnect from BIS and a msg "Modem Mode Enabled" will appear.
As a powerful user, I need my bb to alway connected to BIS while I still want to tethering for the same time.
I saw some tricks at crackberry forum and want to share with U guy.

The step as below:
1) First U need to get into Engineering Screen aka Help Me screen. U can do this by pressing alt+ RIGHT aA +H in homescreen. Screen below will pop up:


2) Then, U need to find out the lock code to go further.
This is the link to generate the lock code: http://dl.dropbox.com/u/9610464/HelpScreen.html
U need to key in all informations as what appear in YOUR Help ME! Screen:


3) Once U got the code, type in the code on the Help Me! screen.

4) If U type in correctly, below screen will appear. Select Multi-WAP Engineering Screen


5) Select Tunnel Engineering Screen


6) Change IP Modem Solo Mode to DISABLE


7) Try tethering your Playbook with your BB, U will see "Modem Mode Enable" but your BB still connected to BIS.

Please aware that there is a RISK to screw up your BB if U dont know and dont follow the above guide. I am not responsible for that. DO IT AT YOUR OWN RISK!!!
