It was all good until i put Transcend 16 GB Micro SD card into my Mini. Phone hanged, Restarted itself and also to be frank my phone was also loaded with Applications, Finally once OS crashed. After re-install, I did not install any application from Market, but again Restarting and hanging started when i tried playing videos shot from my own Mini's camera. So Finally now i have gone back and replaced the 16 GB to my old 2 GB card. Now for 2-3 days it has been good. I just want to know anybody there experienced same problem. Also want to understand was it really due to 16 GB card or applications being overloaded and Finally Is Mini really compatible with 16 GB Micro SD as the specs show it .
