So, I installed a barrel roll app on cydia, and after it restarted the springboard, there was nothing. No slide button or passcode, just my wall paper picture. And when I try to sync with itunes, it says to unlock the iphone, but there's nothing on the screen to unlock.

Hi
My question is based on costs!

I bought the OS X Mountain Lion software for my Macbook today and I was wondering if you could even use your own Iphone number to replace your e-mail to send messages to other Apple devices because I prefer using my Iphone number to text my friends on the messaging app on Mountain Lion.

IPhone 4s 3G network is enabled but not working

Hey ya'll i'm having a problem with my 3G network on my 4S

My original contract phone was Blackberry 9900 and few days ago i sold that and bought myself the IPhone 4s, and i have ordered a new micro sim with the same contract plan that i had on my blackberry, and since i got my Iphone my 3G stopped working. The cellular data is on and everythings else is working perfect. The 3G icon is displayed at the top left but it won't let me access the internet or anything. I rang Three numerous time and did what they told me to do, reset setting, troubleshoot etc. I did all that and still not working

i would appreciate it if someone could help me with this!

Sync new songs to iphone without deleting all the old ones?

I have over 500 songs on my iPhone 4, and most of them were from ripping my dad's CD's.

I do not live at my parents' house anymore, so I no longer have access to these CD's.

My PC's hard drive recently died, leaving me with no music whatsoever. (Yes, I sort of had it all backed up. See it kind of WAS the backup. It had all my music, pictures, games, etc. On it that normally are also on my C:\ drive. Problem is, the backup drive died the night I reformatted and re-installed Windows 7.)

Now the only copies of All of my music are on my iPhone, and iTunes INSISTS on deleting all of it before letting me add anything new to it.

Is there anyway whatsoever I can take all of the music off of the phone first? Or ignore itunes' bull$#! 7? Also, of secondary concern but if at all possible, contacts, photos, notes, etc.

Oh, it is jailbroken.
