Ok so i have a lot of experiance with iOS but have two problems with the iphone4 that I was wondering if someine can help me with. First of all the bluetooth reception sucks, when it is in my car using a2dp if i shake the phone or point the top of the phone towards the back of the car the audio will stutter or fail completely, worked fine on my desire hd but the bluetooth signal seems very weak on the iphone. It is in a case and does the same thing with the case on or off. Any way to improve the bluetooth strength? The other issue is push email with iOS 5.1. I have gmail set up as exchange but it takes about 25 minutes to get my email sent to my device IF i have it set to display mail notifications on the lock screen. If i set them to not being on the lock screen then the notifications are instant. Similarly if i have it set to show them on the lock screen but the phone is unlocked they are instant, there is only a delay when the phone is locked and they are set to display on the lock screen, any ideas about that? I reported the jbug to apple as i assume its the OS but wondered if anyone has a work around. It is a tethered jailbroken phone so a jailbreak tweak would be fine too
