A very good app PhoNetInfo 184.108.40.206 is available for all those who'd like to retrieve technical information about your Windows Phone.
PhoNetInfo retrieves detailed technical phone and network information such as firmware version, device name, battery status, power saving status, network operator, roaming status, wifi/wap interface names, camera details (e.g. ISO, white balance), number of CPUs, CPU architecture, CPU features, CPU page size, high performance timer frequency, time since last device reboot, RAM, etc. All information can be exported by email and the application's language can be changed all the time.
You can download it on the Windows Phone Store by searching for PhoNetInfo.
Unfortunately, I cannot post the link here, as the forum prevents me from posting outside links...
