A lot of people have been disappointed while discovering that the new version of xGPS seems to freeze with some of the supported GPS. We have worked hard to try to correct that bug as fast as possible and we hope to have fixed it. You will find shortly in Cydia a new version numbered 1.2.6 containing this bug fix plus a new spanish translation.
For those who cannot wait the Cydia release, you can find the deb package here: http://xgps.xwaves.net/index.php/Downloads
Thank you all for your support and comments
