a bugs life

so after many attemtps to try to re download all my apps due to them crashing and not loading, I encountered a more serious problem....

Problem number 1:
When I try to delete an app, and succeedsfully do, I reboot my phone... Then after loading and taking me to the main home screen, my apps re appear like if I never deleted them.

Problem number 2:
Everytime I try to open an app (downloaded from the app store), my phone goes back to the main menu. [NOTE: all other apps ore installed work, even those that I SSH'd myself and those downloaded from cydia.]

Problem number 3:
Everytime I try to up into the app store, it tells me that I can't purchase anything because I'm outside the US. WTF?????
I'm in Eagle Pass, Texas!!!!
Even the $ sign was replaced and I saw a £ sign instead! I'm not in Europe!!!

Problem number 4:
iTunes store says the same thing. That I'm outside the US and I can't make a purchase.

Problem number 5:
Apps won't backup to iTunes. Even though I don't want them, I want to back them up to iTunes to avoid downloading them one by one if I get to Re Pwn my iPhone.

Help plz!!!

 

problems continue

problem number 6:
when I try to use safari, it tells me to Turn on Data Roaming, otherwise it won't connect to the Internet. I don't want to get fees for using Data Roaming even though I'm inside the US!!!!

Problem number 7:
My music and videos disapeared when my phone froze after Paralingo crashed my phone. I managed to get them back, but apps won't launch.

Problem number 8:
My labtop won't connect to the Internet after I restored it, which means no iTunes store is availbe at the moment.

Problem number 9:
iPhone freezes after trying to launch Customize.

Problem number 10:
This isn't a problem, but rather a question...
If I erase all content and settings, will my jailbreak be gone? As in back to regular stck mode?

By help will be greatly appreciated!!!
