Hi, after i did this update, when i try to dial a number through a sms message or a webpage, it asks the confimation with the right number but it changes when i dial it. Another problem is that my wifi is not working a 100%, it misses the signal every time, it appears that has just 2 bars in the wifi and it stops, after a while the bar is full and working, but it happens all the time in differents wifi areas. Thanks a lot.
