Unsecured bail means you don' t have to put up the money at the time you are released. The bail is only attempted to be collected if you fail to appear. It's pretty common for magistrates to issue this: I've heard them say "Well this will give you some incentive to make it," or "This will make it worth sending someone after you."
Pleading guilty will "not make this go away."
If you plead guilty, you will still have at least two more court appearances, you'll go to the probation department for a presentence interview. Once convicted, presumably you'd get probation. You'll report weekly to your probation officer. You won't travel more than 50 miles without his permission. You won't drink alcohol or do drugs. You will pay close to $4000 over time in various fees and charges (not counting probably clsoe to $3000 to the lawyer).
NEVER EVER PLEAD GUILTY UNLESS YOU HAVE LEGAL ADVICE TO THE IMPLICATIONS OF DOING SO.
Your best bets are:
1. To have the charges dismissed outright.
2. To have the charges reduced to the summary offense version.
3. ARD
4. Probation.
in roughly that order.
Get an attorney. While you can possibly negotiate ARD with the DA, you'll find most won't want to talk directly to a defendant.
