Hello,
I'm hoping somebody will share some expertise with me, although not quite a technophobe I'm certainly no expert.
Firstly, I'm setting up a wirless network at home so I can get ADSL access for two laptops and would like to be able to use my H3900 (yes I know it's old) as part of the network for file sharing and for internet access.
My question is, would it be better to use a bluetooth router connected to my ADSL router as my PDA has bluetooth built in, or use a CF plugin card via a CF jacket?
I have not always had good experience with Bluetooth, but it seems that using my CF jacket does nothing for processing speed and battery life.
Any info much appreciated.

Secondly, I found some mp3 recording software in the PPCT shop that mentions being able to use an external input rather than the built in microphone.
Being a bit of a bedroom DJ, I'd like to record my mixes straight to mp3
so would like to be able to use a phono connection from my amp/mixer straight in to my PDA!
Now there's only so many holes in my PDA so can I use a phono-3.5mm jack in the headphone socket?
Or am I being stupid?

Sorry for the length of post, but I've been intending to sort this out for a while


Thanks Again
