[...] So its there but (beside a jailbreak which I do have) you'll need some iphone/java related technical skills to get it to work... I hope this is what he's aiming for.
You want an iPhone app that requires the jailbreak and a wonky Java install so you can use it with MapTool?
While that's a great goal, I wouldn't be too excited over it myself (of course, I don't even own an iPhone!). The iPhone's processor is no speed demon so I wouldn't expect zooming and panning to be very quick. (And before you say the iPhone's current apps do just fine, remember that MapTool recalculates
the map viewport for every zoom change and all pans.) And the thing doesn't have a huge amount of memory IIRC, so medium to large maps may be beyond its capabilities.
Of course, I could be wrong about all that. I only know what I've read about the iPhone hardware and I haven't really been paying much attention to it...
