There seems to be a problem .
I installed Duty Taskmanager for Leo. After a soft reset it was working well , but i was not able anymore to sign in on the twitter tab.
So removed taskmanager , soft reset and could reconnect on Twitter .
Probaly some more tweaking to do Duty.
TTS in iGO8 did'nt work anymore on my phone, until I uninstalled this taskmanager.
