More about : upgrading ipaq h4155 r_manic January 14, 2010 1:49:40 AM That depends... is there anything on HP.com indicating that this is possible? Even if you can hack or mod the PDA phone to run pocket pc 2003, I don't think the hardware would be able to handle the demands of the newer OS? Can't find your answer ? Ask !
