Steve,
I had a similar problem with another installer .CAB on our i200's
And this is not necessarily a problem with the device.

I suggest you explore the installer cab, on your PC (basically a zip file) and open the xml file in there with an editor, you will probably find entries like "MaxOSVersion - 5.99" or very similar, and further down this xml file you might find references to a specific processor that is needed.

So what you need to do is to edit this xml file, value 5.99 --> 6.99, and possibly remove the entry regarding the processor.
(Try changing the value first...)

With this edited xml provisioning file in place, you need to recompile the cab.
I would like to recommend you to look for a proper xml editor that will present the xml, as in hives just as in a registry editor. for safe and easy editing

There is also great cab GUI's for cab creations/recompilations.....

Good luck.

PS. Iet us know if you get stuck, and I will let you know more details on editors suitable - names has slipped my mind at the mo.

The Vox (at least mine E650) appears to be a good and stable overclocker.
I noticed that the standard CPU clock is 186Mhz, but i was able to overclock using omapclock to 276Mhz and have it still stable.
I did some test, with SKLite and this is what I got.

with the standard 186Mhz clockspeed:
Integer (hanoi towers): 102.2342 Moves/25 usec
Floating Point (whetstone): 2.565 MWIPS
Internal RAM: 219 speed index
Draw bitmaps: 374 speed index
Main storage (write): 995.46 KB/sec
Main storage (read): 4196.72 KB/sec

On 276Mhz clockspeed increased with OMAP Clock 2:
Integer (hanoi towers): 152.5551 Moves/25 usec
Floating Point (whetstone): 3.824 MWIPS
Internal RAM: 330 speed index
Draw bitmaps: 562 speed index
Main storage (write): 1334.49 KB/sec
Main storage (read): 6269.39 KB/sec
My previous Tornado smartphone was a bad overclocker; already locked up when i increased cpu speed from 181 to 201Mhz.

Off course, overclocking will drain your battery and is can damage your phone. Do with care, and on your own risk. You are warned.
