I've been in touch with the company's export sales manager for a few months now and received an email early this morning about the MID phone's latest and greatest feature: customization. While the slider unit's specs have always included a 4.8" WVGA touchscreen, unspecified AMD Super Mobile CPU, and of course Windows XP (original specs here), a new customized order option (see below) broadens the device's offering with choices of 4.3" and 7" screens, WSVGA resolution, CPU clock speeds of lower or higher than 1GHz, a 5-megapixel camera, and Windows 7.
Pricing for the original model hasn't been released (there's talk of it starting at $500 to $700, depending on configuration), so it's unclear how much higher each of the upgrades would raise the price.
The ITG xpPhone, in whatever form, still doesn't have a confirmed release date, though discussion in the company's forum indicates that the product will hit the market in December. This seems rather unlikely, as preorders are still unpriced and these new customizations would obviously delay production, but we'll just have to wait and see.
