Does anyone know if this app works for UK networks?
June 24th, 2009 at 9:21 am
Hi Tim
I used it yesterday on my iPhone 3G, it works, I was able to use a 3 Mobile Sim card in it as well as my O2 one, I haven’t tested it on any other UK networks as yet.
Cheers

HI. i try add the repo with cydia but when is check the url sya some message like this:

“The indicated repository could not be found.
This could be because you era trying to add a legacy intaller repository (these are not supported). Also ,this interface is only capable of working with exact repository URLs.If you host a repository and are having issues please contact the author of Cydia with any question you have.”

I hope this helps.

to answer your question for Cydia “did not find repository”. That was because the ultrasn0w.com website was down temporarily. With a little bit of patience you should open a browser, enter repo666.ultrasn0w.com and check to see if it is up again. Then at that moment, go to your Cydia, add source, and it should work

Hi Matty
AI only tested it with a data sim card, and it worked ok, I will try it again with a normal one when I get back from holiday and let you know if it works.
