GPS issue in iPod touch after 3.0 update

[CRUZITA]

I am using ipod touch last week i updated ipod to version 3.0. but now i am getting problems in GPS it takes too much time to start GPS and also on the radar I can not find my location ? can someone help me ?

The iPod touch via wifi access points can sometimes determine the location. It may be that it is updated by the 3.0 update and therefore no longer works. It can also be conscious that the access point is removed or otherwise changed. There are also little data in the Netherlands, so it does not really much use.

I also updated to 3.0 yesterday and everything is great except GPS. I Have tried restart by holding down home and lock button, but to no avail: normal switching on/off hasn't worked either. Am reluctant to wipe my phone and restore from backup but not work.
