Most jails don't allow internet access to inmates other than through a pre paid e-mail only system. You would have to get around "prison should be as painful as possible" law and order crowd to get any kind of reform.
This should be classified under "cruel and unusual punishment" as far as I'm concerned. Denying inmates internet access in the information age is like denying inmates access to books in the pre-internet age. Terrible thing to do especially if prison is SUPPOSED to be about rehabilitation, not punishment.
How can it possibly be justified ? If you want them to have ANY job prospects at all when they get out, these people need to be internet-proficient or at least able to use the damn thing. Think about people with 10 or 20+ year sentences, they'll get out without even knowing how to use a computer.
Such cruel, discompassionate madness...
