I don't know if this is the right spot to post or not, if it's not feel free to put it where it should be.

I had an iPhone 3GS 16 GB, with 3.1.3 firmware, and 5.12 bootrom. I jail broke the phone with spirit about a week ago, after installing TomTom, it never worked right, it has my location correct, and if I am driving it shows what it normally would, streets, intersections etc. but it just shows scrambled letters across the screen instead of the street names, and when I try to type in an address, it just gives me more gibberish.

Is anyone else having this problem? or know how to fix it? Thanks

I tried to search but it seems like everyone's problem wit TomTom is not having signal

i took a few pics to show the screen.....
