Hi, all.

Very cool forum here as you can pretty much get any info regarding iphone here, and I am learning TONS~~~
My question is that
Knowing you can jailbreak to put custom sound and ringtones thru ifuntastic and being able to run summerboard on 1.1.1, I really want to try 1.1.1..
Mine is still 1.0.2 and has third party apps (need ebook), but was NOT UNLOCKED, and has never been.
Most of the thread talks about installing third party apps to unlocked 1.1.1 and sounds like you need virginize the phone to do whatever. Doesn't virginizing erases everything like formatting Hard drive?
I am not sure if I want to do that as I don't want to lose the cameral roll pictures and SMS messages.
If you are able to upgrade to 1.1.1 without losing the datat I said, then do you need to uninstall install.app (is that possible?)?
Please somebody give me some clarification.

Thanks in advance.
