Thank you for the reply!!! Does starting off at a "New iPhone" delete contacts as well as the media?
Yes it does, it basically restores your phone to a factory settings, plus jailbreaks it with the Cydia app of course ( being it a Custom 3.1.2 firmware)
If it's too much of a hassle for you to manually enter all your contacts back and if some of your notes and SMS messages have certain value to you that you like to preserve. (understandably so) I say go ahead and use the back up. it may be ok...
But it sounds like you may have heavily customized your phone with lots of Cydia apps, if that's the case then maybe do not restore your Cydia apps/data back up; But just the ones itunes has backed up.
Go ahead and restore from back up if you have to, if you notice any unusual slow downs and behavior (like you are having now) You can always do the same Restoring process over again and this time do a "New Iphone".
Buttom line, it's not too risky to at least try and see if you can restore from back up and DO have your data (Contacts, Calendars SMS messages etc.) all back again.
EDIT: plus what the guy above me said, I have all my iPhone Contacts, Calendar and Notes saved in my MS Outlook program and I use "TreasureMyText" from Cyda right on the iphone to back up those "sentimental" text messages once every few months.
Worst part is...On some apps you are gonna lose the saved data ( ie: games with progression, or more important financial data keeping apps etc. ) I'm sure there are alternate ways to back up those type of data, but it will be a hassle regardless...
Besides those you pretty much just have to "check" and "un-check" your iTunes playlists and other media to sync it with the iphone, as a constant jailbreaker, I basically rely on more than just one source (iTunes) to back up my iPhone data... it's just good peace of mind
