Cellular data not working after software update

cellular-datasoftware

I have updated my iphone software to 6.1 on my 3GS and now my cellular data network is not available. Can this be fixed or can I restore an earlier version again?

I contacted my carrier (o2) and issue was resolved easily. It appears that Data Bolt-On, that I subscribe to, was no longer iPhone compatible. I was advised that this setting was affected by the Software Update. Not sure I really understand how or why but I was assured that the setting had now been amended and data services would be restored at midnight tonight
