I tried this through the "Contact us" link, but after submission, the confirmation pages shows that the web email form is disabled, so posting it here.
I just purchased this app from Cydia (thanks for bringing it back!), but unfortunately, it crashes upon sending an email on an iPad with iOS 4.2.1. This same behavior occurred with the old version (1.0) on this device, but only after a certain iOS version. I don't know which version caused the change. The same behavior is observed on an iPod Touch 2G, iOS version 4.2.1. I did not notice the crash on the Touch with version 1.0 but I'm not certain I used it with iOS 4.2.1 on that device.
In both cases, all export options (ns1, kml and csv) are turned on. I just tested on the Touch, and even with only csv turned on, the crash occurs.
Wigle.net upload works fine, but I use both these devices in wardriving, and need to send myself the traces for research I'm conducting. What logs are kept on the device? I'm happy to send any debugging data you'd like.
