I just received a free axim 5.  I bought the sync/charge cable but it does not seem charge the battery. The power light will flash, go solid, flash, etc.  The power setting sez the battery is charging.   Is there a way to tell if the battery is bad?  It runs fine while connected via USB

Can any ac adapter that fits be used?  and does that charge the battery?

Is there a way to set it up to connect to a wpa wireless network, right now it only seems to see wep?

How do I add a background file?
