You may have to re-install the apn settings - Try Settings then More then Internet settings and a box should appear with different network - make sure to select the correct network as some have two options

Hi,

I agree with Thommo, try to download the APN settings once again. Otherwise, do you mean that there are no connection to the 3G network at all or some functions does not work? Do you see any icon with 3G or H/H+ etc at your signal strenght?

Mm i press there and search for available networks my sim is cosmote so when i choose cosmote 3g or 2g not connecting and doing nothing.. And the small icon 2g or 3g not show.... when inpress to choose network showing registing to.network but do nothing..

Is it exist any option to roll back to previoys version?

[Thommo]

If you want to down grade then this will have to be done manually using a .ftf firmware file and a program called Flashtool - See here for guide on how to create and flash

[tselos]

I do not know.. And will be safer not do something that i donot know.. Any other solution?

But when you tap "Internet settings", do you get any information that the download is complete or that it fails? Otherwise, I suggest that you insert another SIM-card in your phone, download new internet settings to see if you get 3G connection.
