iPhone 3G problem

[Darkipoduser]

Hi guys,
I am having trouble with my iPhone 3G. Whenever I go to the AppStore to download an app, the download button greys out. There no app which I am able to download. I have an iPhone 3G with ios 3.1.2 jailbroken and unlocked using redsn0w. Help appreciated 😉

Try un-jailbreaking. If it works, it's probably due to the jailbreak.

Or maybe you're trying to download an incompatible app.

Is there no other way? (I do not want to lose my data)
