Xperia Z connectivity issues

[rozhy2k]

I have two issues I would like to get some feedback on:

1) When I just bought my Xperia Z, there were no connectivity issues and everything worked just as it should have. After the first update, the phone started to  have trouble with connecting to mobile network data services (GPRS/EDGE/3G/HSPA), despite the fact that the signal was strong and there is a mobile data service in the area. To correct this issue, I have to turn my WiFi and mobile data off and then turn the mobile data back right on. Mobile data is then magically appears and works without a problem. Also, if I do not turn the WiFi off, this trick doesn't seem to work. Once again, this issue appeared only after the first update. The second update didn't fix it, as I was hoping.

2) "Location based Wi-Fi" feature seems to connect to WiFi only when I turn on phone's display. Before I do that, the phone seems to stay on a mobile network data connection, no matter how long I have a working WiFi available in the area. Combined with a the first bug I've described, this often puts me to a state with no connection at all without me even knowing it.

Those two bugs are really frustrating and annoying, making me considering changing the phone.

Please advise on how to fix those issues or would there be a fix in the next update?

I am having the same issue with the Mobile Data of my Xperia Z.  The mobile data goes away after a few minutes, and the only way to bring it back is to turn the phone Off and On again.  This **bleep**.  I have been reading this thread and only one attempt from SONY to respond (which offered no real help IMO).

Firmware and Software have been updated to the latest version, but still having the same problem.  I know for a fact that it is the phone as I have tried my SIM card with another phone and the mobile data connectivity is just fine.

Very, very disappointed with how they support their phone.  And to think that Sony just recently won the most recent Tech Support Showdown from Laptop magazine for their VAIO support.  I have been a Sony fan for quite some time, but this experience is very frustrating in so many ways.
