Both mine (Aug 2010) and wife's (Nov 2010) iPhone4 (32G) suffers higher than normal(than 4.2) battery draining experience (No Personal HotSpot enabled) since upgraded to iOS 4.3 under normal usage condition with Vodafone network.
Also we're having frequent TXT fail to send, very slow to receive from couple days ago in North Shore / Albany Area.
I have to turn it to airplane mode and back to join network to send TXT.
Anyone having similar experience?
