For a while I've been on an ultrasn0w unlocked iPhone 3G S.
The unlock worked fine.

My issue is that whenever I install an app from Cydia, my wi-fi breaks. It's consistent - if I install an app and reboot, wifi's gone!

I've tried the air plane fix, but to no avail. The only thing that seems to work is a network reset.

Is there something the dev-team needs fixing, or can I assume that this is the only way for some of us (I most certainly hope not)?

My phone was bought in the US and is being used in Denmark. The hactivation worked fine and iTunes is registering it correctly, so there's no "problem" there.

What I'm wondering is if there's some other setting/mods I'm missing?
