app development question

[holo]

so I am planning on building an sms-based aim IM client in C# .net (knowing that there are 6 digit numbers you can sms to for login/start chat/checking status/etc) - I just had some questions on interacting with the SMS system on the phone.... aside from a couple of small apps I've done to familiarize myself with programming for it this will be my first windows mobile app so excuse me if my questions are kinda basic

If this isn't the right site for these kinds of questions (I don't see any other development questions here??) can someone please point me to a proper site?

my main question was in intercepting messages - I have found some information on doing this that seems to interface with outlook. my main question here is will this still be doable using the palm threaded sms app? (ie does it intercept all or bypass this and make this useless?)... Also I am having a hard time figuring out exactly how to do the criteria - is it possible to intercept based on the message sender?

if anyone knows the answer to the above question or has some code snippets I could take a look at that either intercept or send messages it would be a GREAT help - or point me to another place that might have more info for me

oh and also does anyone have a solution to the keyboard not working properly in .net apps with the 2.09 sprint rom?
