I have an iP4 but my wife now has my 3G. I never upgraded her phone to 4.x b/c of all the stories on performance, and some say 4.1 took care of that while others I guess say it is still slow. But I have two questions regarding running 4.1 on a 3G, both of which will be quite crucial to her, and if they don't work/aren't supported on the 3G, then it doesn't make sense to upgrade. 1. The 3G does not support Multitasking. I know this. Does it provide any way to screen lock orientation? It drives her crazy that the iPhone switches to landscape cover flow when she sets it down on a table or her car seat or something. 2. Does the update for AVRCP Bluetooth controls for track controls on bluetooth headphones work with a 3G in 4.1? This is one of the features I wanted for so long and was happy to finally get on my iP4 in 4.1. But will 4.1 give her AVRCP on a 3G?
