I just upgraded my T-Mobile iPAQ h6315 to an old firmware I found, the 1.10.08 ENG. but without any T-Mobile logos. After reboot I got the message "Unrecognized SIM Do you want to configure your GPRS/GSM settings?", and thereafter I can not read my contacts from the SIM, even though I can send/receive SMS and calls. Another problem is that every firmware download I have made from HP web side, which I selected to be for the h6315, after trying to install, the software refuse to do so because it is for the h632x...!!! even though I selected the h6315 in the web page before the download. Does any body have the original T-Mobile 1.10.08.ENG or newer upgrade version for the h6315 that works (or a link)? I tried the T-Mobile links in this forum but all of them are not working...!!! I also tried the hp.com links, and the firmware upgrade refuse because of "Incorrect device SKU" and "This upgrade is for HP iPAQ h632x"...!!! I also tried with boot mode (contacs and email buttoms pushed with the hard reset)...Please help.
