I'm using BIS warid and ufone on my bb9780 and bb9700 and its working perfect and I'm using following apps on BIS
Facebook, twitter, googletalk, WLM, yahoo, BBnews, gmail, berryweather, Tapatalk, and many other apps are running in background..
Mobilink BIS is also going smooth one of my friend is using mobilink... I don't know about zong and telenor .... Besides this appworld is not working because Pakistan is not in the whitelist to access appstore ... Applications are different thing and blackberry app world is different thing don't mix them up.... You can access apps easily via wifi and via BIS .... PTA can't block BIS yar many consulates members are dependent on BIS services... Yesterday the appworld was working in pakistan mistakenly just because rim was adding 9 african areas in whitelist for appworld from middle east region luckily we got access to appworld for limited time... Your applications use service books and ur cellular BIS enterprise server while app world use blackberry ID in their RIM servers
