@mpofanaa an iphone personally is in the works. RIM no longer provide a valuable quality of service, this in conjunction with the carriers and their BB APN's.
@brendanc you may be pretty stuck until RIM fix their problem.
@all recommendation: Don't rely on appworld for all your application download requirements. The good thing about app world is that most developers host their own download process or via other stores, such as mobihand, etc.
@RIM hear the pains of the real world, fix this issue quickly and not drag it out.
For everyone that is still having problem with the new App world version 3.1 I have a 100% working solution...1st you must remove/delete your Blackberry protect app then re-install it,sign in with your Blackberry I'd via BB protect then go to your App world and also sign in,it will surely work.If you still have problems email me firstname.lastname@example.org
