Motorola will launch a new phone called Begonia on T-mobile on Nov 1st and it will come with Android 2.2. If you thought you've finally escaped the Blur UI then you're not in luck, because it will also have Blur. Motorola doesn't want to get rid of it so quickly. You can at least be glad that it's Blur 2.0, which has been greatly improved since the first version.
One of the more interesting features is that it will come with Wi-fi calling, something T-mobile has promised before but hasn't delivered until now. The way Wi-fi calling works is no different than the way Skype works through wi-fi. Unfortunately, this means that the only way you'll be able to use this is by talking to another friend who also has this phone or another phone from T-mobile that supports this feature.
This is a very fragmented way to bring wi-fi calling to the masses on Android, which is why Android 3.0 absolutely must have this feature and video-calling as well, like iPhone 4 does.
