I am afraid that it is a no for the Ipaq's, the synchronisation is still poorly supported and catered for, Maximizer only currently 'out of the box' supports Palms, and this is only ideally one way synchronisation PC>Palm, it can go Palm>PC but can make a terrible mess.
But there is WAP access for other Mobile devices via the Web Portals on the eCRM MS SQL version of Maximizer, but at present WAP/WML is the only format catered for, this will enable 'web' access via WAP but as for a fully fledged implementation of Maximizer on a handheld, that would require development for a different OS.
Most of the newer handheld/mobile devices are J2ME JAVA based running on Symbian OS, such as Nokia, Sony, Motorola e.t.c. who own about 80% of the market.
I believe the iPaq is based on Microsoft's [stinger OS] PocketPC.
Maximizers current development language is different to the Symbian OS based devices which are again JAVA (don't mistake for Javascript) and slowly getting support for VB.
Unfortunatly i don't know what languages Microsoft's PocketPC supports
And as such we all wait and see which turns out to be the platform that Maximizer is developed for.
