I'm using Pocketwinc on my iPAQ 4150 and I'm impressed too.
I have the same problem and cannot solve it.
If anyone has a tip I would appreciate it.
With my system it is not possible to get an IP with Pocketwinc until the iPAQ tool got one. This prevents Pocketwinc from checking if a Internet-connection is available.
I think this is worse than the stupid popups every now and then.
Is it possible to turn off the detection with the iPAQ tool?
This would pretty much solve our problem.
Another question: What is with the developer of Pocketwinc? I cannot reach the company website
www.cirond.com.
Maybe there is a solution.
