Been rattling my brain over this one guys.

Setup: iPod 32 gig 3G ios 4.0 Jb 2.0

I have most popular cydia apps installed.

Issue: skype! It works fine on a standard wifi setup. Then when I use my MiFi modem it freezes and pauses on placing call screen.

I tried another pod on 3.1.3 and skype could place the call through the MiFi no problem.

The issue is interesting as the pod still thinks it has a wifi connection. MiFi switches between 3G and HSDPA.

Any thoughts on this?Downgrading isn't an option. I reinstalled mobile-substrate. And tried My3G and 3G unrestrictor.

Any help on this would be most appreciated. Let me know if you need any more data.
