Ya ha sacado Topo el SP1 para la 1.9,
1.9SP1- Introduced vsnet patch from CM: now the phone will sleep correctly also when your network supports fast dormancy (better battery life) and switching between wireless data and wifi does not lead to missing routes.- Some adjustements to SystemUI.apk, but no solution to the USB mass storage icon disappearing when you hit the home key. - Attempt to make USB tethering work (need feedback).
