Usually whenever I see a BlackBerry Bridge update I hope to see a PlayBook OS update but this time it does not look like it will be the case. Jason let us know that RIM has pushed out a tiny update to BlackBerry Bridge bringing it to v18.104.22.168. according to the change log this fixes an issue that I have never heard anyone really complaining about. Supposedly this update:
Addresses an issue where eligible users saw an error that the Bridge Browser was not supported by their wireless service provider.
I personally blame AT&T but I have no proof for that. You should be able to find the update here in App World.
