Configure cellular data on ios 4.1?

[Edvin94]

Hey. I just upgaded fom 4.0.1 to 4.1 and I noticed that the old function where you could configure ure cellular data network is gone in 4.1. I need this configuration to be able to use my network, so I wonder how I can configure my network now that my phone runs 4.1

Does any1 know?

Thanks
