So, I have got the procedure for incorporating a RUIM card into your HTC Touch Pro CDMA Phone.
You can buy the flex cable on ebay from here for just 19.99$ including free shipping - http://cgi.ebay.com/...e=STRK:MEWAX:IT
The video is with me and you can download it here http://rapidshare.com/files/321176601/HTC6850_RUIM_CARD_ASSEMBLE_PROCEDURE_640x480.avi I have converted the 3 minute 300MB video into a 57MB VGA avi file.
Now this procedure does involve little cutting the plastic body and filing for incorporating a perfect fit for your ruim card. In a skilled technician's hand, it should be a 2 minute job. No soldering is required as it incorporates with the micro sd card circuit.
enjoy...
