Newb JB- some post-JB Q's

[Kyoti]

Seen the new untethered jailbreak available yesterday.
I had to update my IP3Gs 32gb running 5.0 to 5.0.1 BB 05.16.05
Was pretty leery of trying this myself. Especially since I am new to smartphones and new to Apple products as well and not really on the techy side. But instructions seemed simple enough, so I took the plunge.
I am happy to say it seems successful. Used redsn0w 0.9.10b1

I have a few questions-

FIXED- the cydia icon is white, is this normal? I seem to recall reading somewhere on here about this subject but cannot recall if it is a problem or if it is normal. Cydia does load though.

- I updated from 5.0 to 5.0.1 but still had apps on the phone after the update. I am afraid I might have lost some space (created wasted space due to not doing a full restore). Though the math is correct - 28.3gb technically available, 6.3gb used, 22gb available. I still have the games on the phone even after the jailbreak. Is this ok? Or did I fudge up somewhere?

- Now that I am jailbroke, do I never hook my phone back up to iTunes?

- I have some ringtones on my iTunes, can I download them onto my phone after jailbreaking?

- And are they any "must haves" apps out there?


But have ran across something I should maybe mention. Before updating to 5.0.1 battery life was horrible (had heard there was a battery draining bug in there), updated to 5.0.1 battery life is better but still not like my IP3gs 16gb is.
- Is it possibly time for a new battery?
- Also, I have seen winterboard and summerboard apps for customization... what is the differences, perks, problems, preference of each?

I read everywhere about "free apps" after jailbreaking but after looking through cydia a bit, I haven't found any free ones.
- Where or how do you get free apps?
- Someone once mentioned to me something about "cydia sources", where do you find this?
- And of course, any other advice is greatly appreciated.

I am contemplating on doing this to my IP3gs 16gb now. But first want to get some help/advice on the rest of my questions above before attempting another jailbreak.

Update:
From a little research, seems like my best option might be codegenocide for repo. I am looking for one that offers games, apps, ringtones & themes.
If you know of one better, please share.
