Arc S ICS sim-lock (pin) and APN problems

[#1]

I had a problem with mobile network APN settings. After Upgrade to ICS I had a working 3G connection, but after less than a week I was unable to use mobile internet. I tired in several different ways to fix APN settings (auto config SMS from provider, manual set and auto config from google servers). Strangely that internet had  been worked KIND OF (just get notifications about facebook changes but can't fully load facebook, can't load web pages or skype, but some internet related notifications worked). Then I found some information on forum that sim-lock (a.k.a PIN) removal could help. And that worked. So I want to inform Sony Ericsson  about this problem. I could give some more information if you tell me how (have some experince in linux bug-tracking and debuging)

We are aware that this was an Android/operator problem back in a older Gingerbread version but I have not noticed it on ICS. I suspect that this might be related to the SIM card. So check if your can use PIN code if you get a new SIM card from you network operator.

Might be since Gingerbread cause that forum topic and solution was about 2.3.x Xperia ray

Btw. The sim is kind of new, changed it at 2011 September. And everything worked fine with 2.3.4.

Btw I can't connect to SSL/HTTPS encrypted pages when connecting via Mobile Network. Everything works with WiFi
