I've jailbroken for this reason, it was the only thing I used on the cydia store (although that was also due to the fact most things were for older versions of iOS and they didn't work)

however, my banking app saw the jailbreak and refused to work... weighing up ease of access to accounts vs colour changing phone... I chose accounts...

now I just avoid my phone in the evenings. -- it's really a shame an app like that doens't make it in to the mainline app store.
