Gaz.... I need your advice again. I have iOS 4.1 on my iPhone4 and would like to upgrade to 4.3 due to the new Hotspot capability. Question: just how big are these iOS upgrades? I have a relatively slow broadband capability (around 1.5 rabps). Will it take me forever to download these new iOS versions? AND........... in your opinion, are these upgrades really stable? I've read horror stories from users after iOS upgrades. Your comments please. Thanks.
