I would love a fellow WinMo'er to take a look at this. This community has soooo many n00b's, it seems challenging to find the people that know stuff. I am in the EXACT same boat as you in terms of trying to get this to do what the TP2 did. I also still have my TP2 and am just trying this out. However the problem i describe in the post i just linked to you makes this phone a total deal breaker. Thanks for the help, and If I can help you in any way, please just ask.
