Iphone 4 stuck on itunes logo?

I have an iphone 4 jailbroken 4.2.1 with LimeRa1n, everytime i turn it off then turn it back on it always ask me to plug it in to itunes that logo in the phone. I use to just plug it in a regular charger then it will turn it on. Now the phone is now completely stuck with the itunes logo, even with my wall charger trick it won't do it anymore. I tried running in dfu mode but still stuck in itune logo. I don't want to do a restore because i would loose all of my kids baby pictures. I have never back it up. Can anybody help me on this issue. I have been doing alot of reading but still no solutions.i'd appreciate all the help i can get.

If all that matters to you are your pictures, you can move them to your computer before restoring using a iOS file browsing program such as iPhone Browser.

Jailbreaking is safe as long as you know what you are doing.

This is an article I wrote on my new website that can help as well.

It is a step by step guide for the "Connect To iTunes" screen.

Why it happens and how to fix it.
