Restore Asus Transformer TF101 original firmware
I have installed a custom firmware on my Asus Transformer TF101 to be able to use my 3G HSDPA USB adapter . It is running Android 3.2.1. Now that the Ice Cream Sandwich firmware (4.0) is released fot the TF101, it’s time to go back to the original, AKA stock, firmware and run the upgrade the “supported” way. According to the forums, there are two ways of doing it. Either restore the bootloader and the firmware using the ClockworkMod or use a Windows/Linux workstation to erase and replace the whole system with the official system. I choose the second option as I didn’t understand how to run the first… and the second option is quite similar to the one I used when I rooted to tab.
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.
