Even if you have been sentenced for a crime, you may be able to post bail and get out of custody during the course of your appeal. Post-conviction bail is not available in all states because it is not a constitutional right.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
Other counties, like Cook County, do not provide online access to criminal records. In this case, go to the Circuit Clerk's Office in the county where your case was filed. Ask the Circuit Clerk for copies of your court dispositions or use the public computer at the courthouse to look them up and print them out.
