iOS 5 Camera, Access from Lock screen on iPhone 4
I’ve just upgraded my iPhone 4 to iOS 5 and was looking for the “Access from Lock screen” feature as it didn’t show up automatically. I was afraid that the feature would not be enabled on the iPhone 4… After a long digging process in the preferences and a quick look on the Internet, I found that the feature was enabled using the “Home” button. In fact, it’s quite easy to use:
Dual SIM on the iPhone 4
Because I have a personal phone and a professional one, I decided to try a double-SIM adapter for the iPhone. I got one from [here]. The iPhone does not have to be jailbreaked ; mine runs the stock iOS 4.3.5. It had to be unsimlocked though as my personal provider is not the same as the one from work. Namely, it worked with both Bouygues Telecom and SFR. You cannot have both SIM available at the same time.
