hi, I have a SonyErixsson X10i with Android 2.1update1 and I see with phpmyadmin than there is only a record for Android 1.6 for this phone.
deviceID = "sonyericsson_x10i_ver1_subua"
user_agent = "Mozilla/5.0 (Linux; U; Android 1.6; xx-xx; X10i Build/R1DA002) AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4 Mobile Safari/523.12.2 (AdMob-ANDROID-20090728)"
So always with phpmyadmin, I create a new record for mine with :
deviceID = "sonyericsson_x10i_ver2_papou"
user_agent = "Mozilla/5.0 (Linux; U; Android 2.1-update1; fr-fr; SonyEricssonX10i Build/2.0.2.A.0.24) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17"
But my phone always show my site like a PC
