Like many other Galaxy Tab 10.1 owners, I was unwilling to wait for the OTA update for Android Ice Cream Sandwich (4.0.4), so I went searching on the NET as soon as I heard that it had been released in Italy. I found these very simple instructions on youtube – there’s no point repeating them here. You can either watch the video, or go straight to the instructions if you’re impatient.

The first thing I noticed after the update was that my 3G no longer worked. Installing a new ROM had wiped out my manually-defined 3G network settings, but putting them back did not work. The WiFi worked OK, though. At first I though I may have erroneously flashed the ROM for the WiFi-only version of the Galaxy Tab (P7510), but that was not the case.

After struggling for about an hour (in which I re-flashed the ICS ROM twice, and considered returning to the previous ROM), it turned out that the ‘Mobile Data’ button was turned off in the notification area – and this is the only place from which you can turn it on/off. I could swear this button did not exist in Honeycomb.

I also noticed that the text-editing area in the Email app is now much wider and makes more sense than in the previous (Honeycomb) version, which was kind of cramped. I use that app a lot, so you’ll understand why I noticed this. And the eBook application no longer works – it says ‘service will be available soon’ when i try to launch it. Could it be network provider dependent?

I will post any other new/strange thing I observe over the course of time.
