Oh great and wise of you out there, a question,

Just like you can expand your number of USB ports on a PC by using a hub is it possible to expand your number of SDIO slots on your Hima (as per the idea of internal dual SIM holders)?

I came across this "mod" (http://homepage.ntlworld.com/david.hutchinson27/pockpc/Pro.htm) where somebody has obviously tried to double up on slots.

Would the concept work for the Hima or as per dual SIM holders does anyone know if there is a product out there already (failled to find on by googling).

FYI I'd love to add WIFI, Storage and GPS to my Hima but don't really want to be forever swapping cards or having combo cards wifi/storage where I'd be stuck once say storage ran out).It would be great to have my current 1G SD storage side by side with a new wifi card both flat against the back of the hima (inside or out space allowing) then I could pop the GPS SD into the top since that's the bulky one).

Thoughts/ insights much appreciated.

PS posted this over in buzzdev too and the feedback seemed to be positive on the theory but nothing re a product out there already or anybody else trying the same thing.

Hi Rudegar,

Thanks for the reply but I think you miss understand me. did you follow the link embedded in the "mod" text in my post above?

I'm not wanting to connect USB devices to my Hima. Instead I'm wanting to connect multiple SDIO cards at the same time (e.g. Wifi, Memory and GPS). The link I supplied showed how this was done on another pda via an aweful hack of the hardware. It seemed to work (albeit messy and probably not very robust) so I'm trying to see if there is a product or procedure out there which will work for our Hima's.

Suggestions so far have been to use a miniSD adapter to help bring the SDIO contacts out from inside the Hima (hnce hosting a splitter connection), strip a muliple card reader to donate card hardware or try to utilise the other I/O connections that the backpack uses. All of this is beyond my scope so I'm seeing if anyone else has contemplated adding more than 1 SDIO card to their hima simultaneously.

My analogy was to refer to a PC's ability with only one USB port to use multiple USB devices simultaneously via a USB hub. I'm not looking to attached USB devices to my Hima.

Any thoughts on the multi-SDIO idea?
