Hello everyone. I'm new in this forum and i have a question if someone could help. Is it possible to make the tomtom 1.7 app to run in a lower resolution mode on iphone 4? it's a bit laggy. I've tried the same version in a 3gs and it runs smoothly because of the resolution. If i install an older version of tomtom like 1.4.1 it runs mutch better but without retina resolution. I have an iphone 4 with ios 4.3.3 Thanks in advance.
