You can't use over the air and will have to connect it to iTunes to update. The update will remove your jailbreak

Yes

Maybe, depends on what packages (jailbroken apps) you download

Just be safe with what you're downloading, check on the Internet if the app/package is safe

Hope I helped

Generally, Cydia apps from the main (pre-stored) Cydia repos are safe. I, who install almost all new, interesting hacks, haven't never had any problems with their info stealing etc.

Just don't use pirated Cydia apps - noone knows what THEY can contain.

The 4S is a beast especially when jailbroken. When jailbreaking first started it pushed the limit on older devices. But the 4S is so powerful that you can install quite a bit of extensions and still have it running smoothly. I used to keep my extensions light but I've noticed that even if I install more and more, my phone doesn't get leggy or nothing. It's truly amazing. Just make sure you install legal, compatible, and most importantly non-conflicting packages from cydia and you'll be fine!

JBing is so awesome, that I prefer my JB i4 over a stock 4s. With fakeclockup, its simply snappier in addition to all the other tweaks I have.

I agree. I've had my 4S jailbroken for about six months now, no lag, no freeze ups, using the Absinthe jailbreak. This is by far the cleanest JB I've had on an iOS device.
