The image you see below represents a screengrab of a Bell system which was leaked to MobileSyrup. As you can undoubtedly make out, the Samsung Galaxy Gio will become available at Bell on August 4, according to it.
We have no reason to doubt this image's authenticity, and given that August 4 is so close, we don't expect there to be any (big) delays. So it looks like you'll be able to go to your local Bell store and purchase a Galaxy Gio starting next Thursday.
