I am kinda noob with this. I have bought (in transit) a O2 XDA Neo from shopping.indiatimes.com, will it support airtel network in hyderabad???...and it has Windows Mobile 5, will i be able to use most of the Wm5 applications available??
ROM is a place where the operating system resides. Different ROM-makers change different settings in OS, install different apps and thus build their version of ROM. Its like different flavors of Linux distros (each with different settings/apps but the base is the same)
Pagepool is like cache memory that we have on pc's. Probably technically it might be different, but basically it means the same.\
User-Customizability capability implies the facility where the user can install apps directly from the cabs stored in memory card after a format / reinstall.
Radio is that part of OS that communicates with cellular network (calling, gprs etc.)
No idea about this. Never used something like this before.
There are some guides explaining how to do it on Vista. I have never taken any chances, because unlike iPhone, win-mo phones *CAN* get bricked. So be careful.
You can install them once your new ROM is installed.
Any time. Does not matter.
