well i found a little bug in the system ... sometimes my wazapp works perfectly but from one second to the other it suddenly stops working , i cant send or receive any messages anymore and it doesn't show if the person is online or not but it tells me i would be online, rebooting the device didn't work, turning to airplane mode and back online didn't work, removing the sim didn't work... i am running out of ideas here ... also my Emails stopped working the same time, but every other sevice (facebook & twitter) works perfectly... anyone else experienced that ? oh and i used only 3G
