Hello! I have an O2 XDA II Mini phone which originally came with Windows Mobile 2003 OS, and the specs are 64 MB RAM and 416 Mhz CPU. I've recently installed Windows Mobile 6.1 on it and suprisingly it works perfectly. So my question is, does my Pocket PC meet the minimum system requirements to run Windows Mobile 6.5, when knowing the fact that Windows Mobile 6.1 works fast and stable? Thanks!
