As i've read in this -or another - forum, you can copy in the SD Card a file called SonyEricssonP80xPlatform.sis from a P800 and then the A920 thinks that he is a P800 and so, you can install apps without checking the 3 certificate.....
Well, I've tried to do that but it doesn't work!!
I don't know if it happens because the information was not correct, or because yo need to upgrade the handset to a 925 before doing that trick....
Add to all of this that I'm in Spain and we've no 3 network and Motorola haven't got this handset on my country, so... I'm very desperate.
Please, help
Thanks
