Samsung bada 2.0 coming in September, 1.2 update won't be pushed to WQVGA phones30
At the same time, bada 2.0 was confirmed to be on track for a September release in various countries. The release will introduce multitasking and an overhauled UI among other new features. “But the schedule can be changed,” Samsung warned about a possible delay. The Samsung Wave and Wave II will be some of the devices which are sure to be updated. In addition, the SDK for the next big bada will be released in Q3 as well.
Finally, asked whether the platform will support VoIP applications like Skype, Samsung couldn't confirm about those, so our guess is that for the time being you'll have to make do without them.
